# OpenPGP Class The OpenPGP class is used to encrypt/decrypt and sign/verify PGP messages. ## Class Name **IPWorksPGP_OpenPGP** ## Procedural Interface ```text ipworkspgp_openpgp_open(); ipworkspgp_openpgp_close($res); ipworkspgp_openpgp_register_callback($res, $id, $function); ipworkspgp_openpgp_get_last_error($res); ipworkspgp_openpgp_get_last_error_code($res); ipworkspgp_openpgp_set($res, $id, $index, $value); ipworkspgp_openpgp_get($res, $id, $index); ipworkspgp_openpgp_do_config($res, $configurationstring); ipworkspgp_openpgp_do_decrypt($res); ipworkspgp_openpgp_do_decryptandverifysignature($res); ipworkspgp_openpgp_do_encrypt($res); ipworkspgp_openpgp_do_getrecipientinfo($res); ipworkspgp_openpgp_do_interrupt($res); ipworkspgp_openpgp_do_reset($res); ipworkspgp_openpgp_do_sign($res); ipworkspgp_openpgp_do_signandencrypt($res); ipworkspgp_openpgp_do_verifysignature($res); ``` ## Remarks The OpenPGP class supports encrypting/decrypting and signing/verifying OpenPGP messages. Supported message formats are specified by [RFC 4880](https://datatracker.ietf.org/doc/html/rfc4880), in addition to [RFC 9580](https://datatracker.ietf.org/doc/rfc9580/), which introduces support for OpenPGP Version 6. GnuPG (2.5.x and later) uses its own Version 5 message format (LibrePGP). The class supports creating and processing LibrePGP-formatted messages as well, for interoperability with GnuPG. See [CompatibilityProfile](#CompatibilityProfile) for details on choosing between the two formats. The [Encrypt](#encrypt-method-ipworkspgp_openpgp-class), [Sign](#sign-method-ipworkspgp_openpgp-class), and [SignAndEncrypt](#signandencrypt-method-ipworkspgp_openpgp-class) methods are used to create a message to be sent to your partner. You can additionally create messages bound for multiple recipients with different keys, simultaneously encrypt and compress with the most popular compression algorithms, and control other aspects such as the encrypting algorithm to use. When a message is received, the [Decrypt](#decrypt-method-ipworkspgp_openpgp-class), [VerifySignature](#verifysignature-method-ipworkspgp_openpgp-class), and [DecryptAndVerifySignature](#decryptandverifysignature-method-ipworkspgp_openpgp-class) methods are used to process the incoming message. The Keys property holds the key (with private key) used to sign and decrypt. The SignerKeys property holds the key used to verify a signature. The RecipientKeys property holds the key used to encrypt. **Input and Output Properties** The class will determine the source and destination of the input and output based on which properties are set. The order in which the input properties are checked is as follows: - [InputFile](#inputfile-property-ipworkspgp_openpgp-class) - [InputMessage](#inputmessage-property-ipworkspgp_openpgp-class) When a valid source is found the search stops. The order in which the output properties are checked is as follows: - [OutputFile](#outputfile-property-ipworkspgp_openpgp-class) - [OutputMessage](#outputmessage-property-ipworkspgp_openpgp-class): The output data is written to this property if no other destination is specified. ## Property List *The following is the full list of the properties of the class with short descriptions.

The *PercentProcessed* parameter indicates the current status of the operation. The *BytesProcessed* parameter holds the total number of bytes processed so far. The *Operation* parameter is only applicable when either [ReadFromProgressEvent](#ReadFromProgressEvent) or [WriteToProgressEvent](#WriteToProgressEvent) is set to True. This parameter defines whether a Read or Write operation is required. If the configuration settings are not set this parameter will always return 0. Possible values are: | | | | --- | --- | | 0 | None | | 1 | Read | | 2 | Write | The *IsEOF* parameter is only applicable when either [ReadFromProgressEvent](#ReadFromProgressEvent) or [WriteToProgressEvent](#WriteToProgressEvent) is set to True. This parameter defines whether the Read or Write operation is complete. When the *Operation* is Read (1) this parameter must be set to indicate that all data has been supplied to the class. When the *Operation* is Write (2) this value may be queried to determine when all data has been processed. # RecipientInfo Event ([IPWorksPGP_OpenPGP](#openpgp-class) Class) Fired for each recipient key of the encrypted message. ## Object Oriented Interface ```text public function fireRecipientInfo($param); ``` ## Procedural Interface ```text ipworkspgp_openpgp_register_callback($res, 4, array($this, 'fireRecipientInfo')); ``` ## Parameter List ```text 'keyid' 'fingerprint' 'publickeyalgorithm' ``` ## Remarks This event fires when the [Decrypt](#decrypt-method-ipworkspgp_openpgp-class) or [DecryptAndVerifySignature](#decryptandverifysignature-method-ipworkspgp_openpgp-class) method is called. *KeyId* is the hex-encoded 4- or 8-byte Id of the key used to encrypt the message. If a subkey was used to encrypt the message this will be the Id of that subkey. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's *Fingerprint*. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's *Fingerprint* instead. For instance: ```text 5E70662EA810E768 ``` *Fingerprint* holds the hex-encoded, 20-byte fingerprint of the key. This is in the form: ```text 5E70662EA810E768391A2FE8F7B7D49C89C9D7B1 ``` The *KeyId* and *Fingerprint* parameters can be used to identify the correct key to specify in the **Key*** properties. The **Key*** properties can be set from within this event as this event fires directly before the decryption process begins. It is recommended to use the *Fingerprint* to identify the correct key, as it is possible for different keys to have the same *KeyId*. *PublicKeyAlgorithm* is the algorithm of the public key used to encrypt the message. Possible values are: - *RSA* - *DSA* - *ECDSA* - *EdDSA* - *Ed25519* - *Ed448* - *RSA-Legacy* - *ECDH* (Subkeys only) - *X25519* (Subkeys only) - *X448* (Subkeys only) - *ML-KEM* (Subkeys only; LibrePGP/GnuPG) - *ML-KEM-768+X25519* (Subkeys only) - *ML-KEM-1024+X448* (Subkeys only) # SignatureInfo Event ([IPWorksPGP_OpenPGP](#openpgp-class) Class) Fired during verification of the signed message. ## Object Oriented Interface ```text public function fireSignatureInfo($param); ``` ## Procedural Interface ```text ipworkspgp_openpgp_register_callback($res, 5, array($this, 'fireSignatureInfo')); ``` ## Parameter List ```text 'keyid' 'fingerprint' 'signingalgorithm' 'publickeyalgorithm' ``` ## Remarks This event fires when the [VerifySignature](#verifysignature-method-ipworkspgp_openpgp-class) or [DecryptAndVerifySignature](#decryptandverifysignature-method-ipworkspgp_openpgp-class) method is called. It provides information about the signature of the message. *KeyId* is the hex-encoded 4- or 8-byte Id of the key used to sign the message. If a subkey was used to sign the message this will be the Id of that subkey. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's *Fingerprint*. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's *Fingerprint* instead. For instance: ```text 5E70662EA810E768 ``` *Fingerprint* holds the hex-encoded, 20-byte fingerprint of the key. This is in the form: ```text 5E70662EA810E768391A2FE8F7B7D49C89C9D7B1 ``` The *KeyId* and *Fingerprint* parameters can be used to identify the correct key to specify in the **SignerKey*** properties. The **SignerKey*** properties can be set from within this event as this event fires directly before the verification process begins. It is recommended to use the *Fingerprint* to identify the correct key, as it is possible for different keys to have the same *KeyId*. *SigningAlgorithm* describes the hash algorithm used when the message was originally signed. This value is applicable only to the message signature, not the key used to sign the message. Possible values are: - *SHA1* - *MD5* - *SHA256* - *SHA384* - *SHA512* - *SHA224* - *RIPEMD160* - *SHA3-256* - *SHA3-512* *PublicKeyAlgorithm* is the algorithm of the public key used to sign the message.

It may be used to track the progress of an operation. The level of detail is controlled by the [LogLevel](#LogLevel) setting. # VerificationStatus Event ([IPWorksPGP_OpenPGP](#openpgp-class) Class) Fired after verification of the signed message. ## Object Oriented Interface ```text public function fireVerificationStatus($param); ``` ## Procedural Interface ```text ipworkspgp_openpgp_register_callback($res, 7, array($this, 'fireVerificationStatus')); ``` ## Parameter List ```text 'keyid' 'fingerprint' 'status' ``` ## Remarks This event fires when [VerifySignature](#verifysignature-method-ipworkspgp_openpgp-class) or [DecryptAndVerifySignature](#decryptandverifysignature-method-ipworkspgp_openpgp-class) is called. It provides information about the result. *KeyId* is the hex-encoded 4- or 8-byte Id of the key used to sign the message. For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's *Fingerprint*. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's *Fingerprint* instead. For instance: ```text 5E70662EA810E768 ``` *Fingerprint* holds the hex-encoded, 20-byte fingerprint of the key. This is in the form: ```text 5E70662EA810E768391A2FE8F7B7D49C89C9D7B1 ``` *Status* holds the result of the operation. Possible values are: | | | | --- | --- | | 0 | Verification succeeded | | 1 | Verification failed | | 2 | The required key could not be found | | 3 | Verification succeeded but the key is expired. | # Config Settings ([OpenPGP](#openpgp-class) Class) The class accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these *internal properties* is provided through the [Config](#config-method-ipworkspgp_openpgp-class) method. ### OpenPGP Config Settings **AEADChunkSizeExp**: Specifies the exponent used to calculate the plaintext chunk size for encryption.This config specifies the exponent used to calculate the plaintext chunk size for encryption. Note this config is only applicable when [EncryptingAlgorithm](#encryptingalgorithm-property-ipworkspgp_openpgp-class) is set to *AES*-OCB* or *AES*-GCM* (AEAD encryption algorithms). By default, this value is *6*. Valid values range from *6* to *22*. The chunk size is calculated as 2^exp (in octets, or bytes), where exp is the value of this configuration setting. For example, the default chunk size would be: 2^(6) = 64 bytes. In this case, the plaintext would be split into chunks of 64 bytes, each of which will be individually encrypted using the specified [EncryptingAlgorithm](#encryptingalgorithm-property-ipworkspgp_openpgp-class). **AllowEmptyInput**: Whether to allow empty files for input.This setting controls whether the class allows empty input when processing. When True, the class will process 0 byte files specified by [InputFile](#inputfile-property-ipworkspgp_openpgp-class), or 0 byte messages specified by [InputMessage](#inputmessage-property-ipworkspgp_openpgp-class). The default value is False. **AllowOldPacketType**: Whether to allow the older encrypted packet type.By default the class will only encrypt data using the newer and more secure integrity protected data packet type. Old implementations such as PGP 6.5.8 may require the older less secure data packet type. When set to True the class will read the features from the recipient key to determine if the older packet type is required. If the key does require the old packet type, then the older packet type will be used. If the key does not require the old packet type, then the new integrity protected packet type will still be used. By default this value is False. This means under no conditions is the older less secure packet type used. The newer integrity protected packet type is always used. Only enable this setting if you have a requirement to do so. **Argon2Iterations**: Specifies the number of iterations used for Argon2.This configuration setting specifies the number of iterations performed for passphrase-based key derivation during symmetric encryption/decryption. Note that this configuration setting is only applicable when [UseArgon2](#UseArgon2) is *True* and [SymmetricPassphrase](#SymmetricPassphrase) is specified. The default value is *3*. Valid values range from 1 to 2^(32)-1. Higher values provide more brute-force protection for the key passphrase at the cost of performance. This configuration can be used to tune the running time independently of the memory size (see [Argon2MemorySizeExp](#Argon2MemorySizeExp)). **Argon2MemorySizeExp**: Specifies the exponent used to calculate the memory size used when creating a key.This configuration setting specifies the exponent used when calculating the memory size used for passphrase-based key derivation during symmetric encryption/decryption. Note that this configuration setting is only applicable when [UseArgon2](#UseArgon2) is *True* and [SymmetricPassphrase](#SymmetricPassphrase) is specified. The default value is *16*. Valid values range from 3 to 31, though the minimum can vary depending on the value of [Argon2Parallelism](#Argon2Parallelism) (see below). The memory size (in KB) is calculated as 2^exp, where exp is the value of this configuration setting. For example, the default memory size would be: 2^(16) = 65,536 KB. NOTE: The memory size must be an integer number of kilobytes ranging from 8*p to 2^(32)-1, where p is the value of [Argon2Parallelism](#Argon2Parallelism). Therefore, [Argon2MemorySizeExp](#Argon2MemorySizeExp) must be an integer ranging from 3+ceil(log2(p)) to 31. For example, if [Argon2Parallelism](#Argon2Parallelism) is set to *8*, valid values for [Argon2MemorySizeExp](#Argon2MemorySizeExp) range from *6* to *31*. **Argon2Parallelism**: Specifies the degree of parallelism used for Argon2.This configuration setting specifies the degree of parallelism, or the number of lanes, used for passphrase-based key derivation during symmetric encryption/decryption. Note that this configuration setting is only applicable when [UseArgon2](#UseArgon2) is *True* and [SymmetricPassphrase](#SymmetricPassphrase) is specified. The default value is *4*. Valid values range from 1 to 2^(24)-1. **CloseInputStreamAfterProcessing**: Determines whether or not the input stream is closed after processing.Determines whether or not the input stream set by SetInputStream is closed after processing is complete. The default value is True. **CloseOutputStreamAfterProcessing**: Determines whether or not the output stream is closed after processing.Determines whether or not the output stream set by SetOutputStream is closed after processing is complete. The default value is True. **CompatibilityProfile**: Specifies the OpenPGP compatibility profile used when creating messages.This setting specifies the OpenPGP compatibility profile used when creating messages via [Encrypt](#encrypt-method-ipworkspgp_openpgp-class), [Sign](#sign-method-ipworkspgp_openpgp-class), and [SignAndEncrypt](#signandencrypt-method-ipworkspgp_openpgp-class). Possible values are: | | | | --- | --- | | RFC9580 | Creates messages using RFC 9580 formats, including v6 session key packets, RFC 9980 composite ML-KEM recipient keys, and v2 SEIPD packets when AEAD is used. This is the default. | | LibrePGP | Creates messages compatible with GnuPG's LibrePGP format, including GnuPG ML-KEM recipient keys, v5 symmetric-key session key packets, and OCB Encrypted Data packets when AEAD is used. | Set this to match the format of the keys involved in the operation, rather than as a fixed preference: - When encrypting with a recipient key, or signing with a key, that was generated by GnuPG (2.5.x or later) or otherwise uses the LibrePGP key format (see the [KeyMgr](KeyMgr.md#KeyMgr) classes *KeyVersion* setting), set this to *LibrePGP*. This also restricts AEAD encryption to the OCB algorithm, since that is the only AEAD algorithm GnuPG supports. - When the keys involved are RFC 9580 keys not tied to GnuPG, leave this at the default, *RFC9580*. Unlike the [KeyMgr](KeyMgr.md#KeyMgr) class, there is no separate key/packet-version setting here: [CompatibilityProfile](#CompatibilityProfile) alone determines which packet version is written for session keys and signatures when a message is created. This setting only affects the format of messages the class generates. Decrypting and verifying existing messages (via [Decrypt](#decrypt-method-ipworkspgp_openpgp-class) and [VerifySignature](#verifysignature-method-ipworkspgp_openpgp-class)) supports both RFC 9580 and LibrePGP formats regardless of this setting. **CompressionLevel**: The level of compression used.This setting specifies the level of compression used: possible values depend on the value of [CompressionMethod](#compressionmethod-property-ipworkspgp_openpgp-class) and are detailed below. This value is passed directly to the underlying compression library: | | | | --- | --- | | zlib | -1 (library default), or 0-9 | | zip | -1 (library default), or 0-9 | | bzip2 | 1-9 | For *zlib* and *zip*, -1 requests the library's own default compression level (typically equivalent to *6*). For *bzip2*, which has no native default level, a value of -1 is treated as *4*. Higher values (other than -1) cause the class to compress better; lower values cause it to compress faster. The default value is -1. **DeleteOutputFileOnError**: Whether to delete the output file on an error.Set this to true to automatically delete any partially written [OutputFile](#outputfile-property-ipworkspgp_openpgp-class) if an error occurs. The default is *false* **DetachedSignatureData**: The detached signature.This setting is used to specify the detached signature before calling [VerifySignature](#verifysignature-method-ipworkspgp_openpgp-class). The message data should be specified normally and this setting should be set to the detached signature data. Both hex-string and OpenPGP ASCII-armored message formats are allowed. Hex-encoded data should be provided as a string like so: ```text 89011C04000102000605025100459B000A0910E2... ``` **EnsureValidDSASignatureHashAlgorithm**: Whether or not to select a suitable signature hash algorithm automatically.This setting specifies whether the class ensures a valid hash algorithm is selected for use with the loaded DSA or ECDSA key. The default value is True. ## DSA Notes DSA requires that the hash be 160 bits or larger, which means MD5 is not a suitable algorithm. When DSA Signature Hash Algorithm selection is enabled (default) the class will use the preferred algorithm from the key if it meets the requirements for DSA. If the preferred algorithm is MD5 and does not meed the requirements for DSA the class will automatically use a suitable algorithm based on the Q element of the DSA key (may be SHA1, SHA224, or SHA256). ## ECDSA Notes The ECDSA Signature Hash Algorithm requirements are directly related to the [KeyCurve](#keycurve-property-ipworkspgp_openpgp-class) used by the key. When this setting is enabled (default) the class will use the preferred algorithm from the key if it meets the requirements for ECDSA. If the preferred algorithm does not meet the requirements the class will automatically select a valid hash algorithm based on the curve as follows: | Curve | Hash Algorithm | | --- | --- | | secp256r1 | SHA256 | | secp384r1 | SHA384 | | secp521r1 | SHA512 | | secp256k1 | SHA256 | **FileName**: The original name of the encrypted file.When encrypting, this configuration setting can be used to specify the original name of the encrypted data. When specifying an [InputFile](#inputfile-property-ipworkspgp_openpgp-class) to encrypt from, this is included automatically in the encrypted packet. After decrypting, this will contain the file name of the original encrypted file. **KeyIdLength**: The length of the KeyId available.This controls the length of KeyId available when [RecipientInfo](#recipientinfo-event-ipworkspgp_openpgp-class) fires. Possible values are 4 or 8 (default). For OpenPGP v4 keys and earlier, the key Id corresponds to the last 4 or 8 bytes of the key's *Fingerprint*. For OpenPGP v6 keys, the key Id corresponds to the first 8 bytes of the key's *Fingerprint* instead. For instance: ```text 5E70662EA810E768 ``` **KeySelectionMethod**: The method used to select a key for encryption or signing.When more than one key is present this class can be configured to automatically select a key based on certain criteria (described below) or allow for manual selection. | | | | --- | --- | | 0 | Automatic selection, first suitable subkey. Expired keys accepted. | | 1 | Automatic selection, first suitable subkey. Expired keys not accepted. | | 2 | Automatic selection, newest suitable subkey. Expired keys not accepted (Default). | | 99 | Manual Selection. | A key's suitability is determined by its usage flags. *Manual Selection* To manually select a key for any operation pass the key's Id in the constructor. ```text Openpgp pgp = new Openpgp(); pgp.Config("KeySelectionMethod=99"); pgp.RecipientKeys.Add(new Key(@"C:\path\to\key.asc", "7CA1376C39768977")); // Key with Id 7CA1376C39768977 will be used for encryption. ``` **LogLevel**: Specifies the level of detail that is logged.This setting controls the level of detail that is logged through the [Status](#status-event-ipworkspgp_openpgp-class) event. Possible values are: | | | | --- | --- | | 0 (None) | No events are logged. | | 1 (Info - default) | Informational events are logged. | | 2 (Verbose) | Detailed data is logged. | | 3 (Debug) | Debug data is logged. | **PGPZipDir**: The directory used when creating or extracting a PGP zip file.A PGP zip file is a Tar archive that is encrypted. It is commonly used by utilities to protect multiple files in one OpenPGP message. The class supports creating and extracting these types of files. - To create a PGP zip file set this value to a location on disk including a filemask and call [Encrypt](#encrypt-method-ipworkspgp_openpgp-class). For instance: ```text OpenPGP1.Config("PGPZipDir=C:\MyFiles\*.txt"); OpenPGP1.OutputFile = "C:\PGPZip.pgp"; OpenPGP1.Encrypt(); ``` The created file returned in the [OutputFile](#outputfile-property-ipworkspgp_openpgp-class) property is the PGP zip. If [InputFile](#inputfile-property-ipworkspgp_openpgp-class) is specified it is used to temporarily hold the Tar archive while creating the PGP zip file. The temporary file is not automatically deleted. If [InputFile](#inputfile-property-ipworkspgp_openpgp-class) is not specified the Tar archive is held in memory while creating the PGP zip file. - To extract a PGP zip file set this value to a location on disk and call [Decrypt](#decrypt-method-ipworkspgp_openpgp-class). For instance: ```text OpenPGP1.Config("PGPZipDir=C:\MyFiles"); OpenPGP1.InputFile = "C:\PGPZip.pgp"; OpenPGP1.Decrypt(); ``` The extracted files will be present in the specified directory. If [OutputFile](#outputfile-property-ipworkspgp_openpgp-class) is specified it is used to temporarily hold the Tar archive. The temporary file is not automatically deleted. If [OutputFile](#outputfile-property-ipworkspgp_openpgp-class) is not specified the Tar archive is held in memory while extracting the PGP zip file. Note that if the OpenPGP message supplied is not a PGP zip file the decryption will occur as normal without error. **ProgressEventThreshold**: The amount of data in bytes to process before firing the progress event.When encrypting or decrypting, the [Progress](#progress-event-ipworkspgp_openpgp-class) event is fired as data is processed by the class. When this setting is specified, the event will only fire after processing at least the specified number of bytes. The default value is 0. **PublicKeyringFile**: The file name of the public keyring file.This specifies the name of the public keyring file. The default value is "pubring.gpg". This may be set to a file name only, or a full path including the file name. **ReadFromProgressEvent**: Whether to read input data from inside the progress event.When set to True this setting allows input data to be specified from within the [Progress](#progress-event-ipworkspgp_openpgp-class) event. The class will repeatedly fire the [Progress](#progress-event-ipworkspgp_openpgp-class) event to ask for data. Inside the event set [InputMessage](#inputmessage-property-ipworkspgp_openpgp-class) when the *Operation* parameter of the event is 1 (Read). When all data has been provided set the *IsEOF* parameter of the event to True. This allows input data to be chunked and provided piece by piece. The default value is False. **RecursiveDecryptMode**: Whether the encrypted data should be decrypted recursively.In some instances data will be encrypted multiple times. This configuration option determines how the class will handle this situation. Options are: | | | | --- | --- | | 0 | Automatic - If the PGP message contains the special header version "PGP Command Line" then recursive decryption will be attempted. (Default) | | 1 | Always attempt recursive decryption. | | 2 | Never attempt recursive decryption. | **RequireEncryption**: Whether to throw an error when decrypting and encryption is not detected.By default, the component's decryption methods will succeed if the message is not encrypted. To cause an error to be thrown in this case, set this option to true. The default value is false. **RequireIntegrityProtectedPacket**: Whether an MDC packet is required for decryption.When set to true, the class will throw an exception if the message being decrypted does not contain a Message Detection Code (MDC) packet. The default value is false. **RequireSignature**: Whether to throw an error when verifying a signature and no signature is found.By default, the component's signature verification methods will succeed if the message is not signed. To cause an error to be thrown in this case, set this option to true. The default value is false. **RequireValidSignature**: Specifies if an invalid signature is considered an error condition.By default, if the signature is not valid the class fails with an error. This setting may be set to False to disable this requirement. When False, the *Status* parameter of the [VerificationStatus](#verificationstatus-event-ipworkspgp_openpgp-class) event should be checked to determine the result of the operation. The default value is True. **S2KAlgorithm**: Specifies the algorithm for S2K key derivation.Specifies the S2K algorithm used to derive encryption keys from passphrases. Possible values are: - SHA1 (default) - MD5 - SHA256 - SHA384 - SHA512 - SHA224 - RIPEMD160 - SHA3-256 - SHA3-512 **S2KIterations**: Sets the number of iterations for S2K key derivation.Defines the number of iterations for the String-to-Key (S2K) function, affecting key derivation strength. By default, this value is *96*. Valid values range from *0* to *255*. **SecretKeyringFile**: The file name of the secret keyring file.This specifies the name of the secret keyring file. The default value is "secring.gpg". This may be set to a file name only, or a full path including the file name. **SplitHeaders**: Controls whether ASCII Armor headers are split or not.By default, when headers are specified via MessageHeaders, the class will split headers over a certain length onto multiple lines. This is done to avoid potential errors during transport of the message. If false, the headers will be on one line regardless of length. The default value is True. **SymmetricPassphrase**: The password used for symmetric encryption or decryption.This setting specifies the passphrase when using symmetric encryption. If a value is provided, symmetric encryption/decryption will be attempted. In this case no keys are used for either encryption or decryption. Only [Encrypt](#encrypt-method-ipworkspgp_openpgp-class) and [Decrypt](#decrypt-method-ipworkspgp_openpgp-class) are valid operations when a value is set. [Sign](#sign-method-ipworkspgp_openpgp-class), [SignAndEncrypt](#signandencrypt-method-ipworkspgp_openpgp-class), [VerifySignature](#verifysignature-method-ipworkspgp_openpgp-class), and [DecryptAndVerifySignature](#decryptandverifysignature-method-ipworkspgp_openpgp-class) are not valid operations when using this option. **UseArgon2**: Whether to use Argon2 for key derivation during symmetric encryption or decryption.Determines whether the Argon2 algorithm is used as the String-to-Key (S2K) method for passphrase-based key derivation during symmetric encryption/decryption. The default value is *False*. This configuration is only applicable when [SymmetricPassphrase](#SymmetricPassphrase) is specified and when calling [Encrypt](#encrypt-method-ipworkspgp_openpgp-class) or [Decrypt](#decrypt-method-ipworkspgp_openpgp-class). Additionally, the following configuration settings are applicable when this config is set to *True*: - [Argon2Iterations](#Argon2Iterations) - [Argon2Parallelism](#Argon2Parallelism) - [Argon2MemorySizeExp](#Argon2MemorySizeExp) Note that if [UseArgon2](#UseArgon2) is enabled, [EncryptingAlgorithm](#encryptingalgorithm-property-ipworkspgp_openpgp-class) must be specified as an AEAD encryption algorithm (e.g., *AES192-OCB*). Please see the [EncryptingAlgorithm](#encryptingalgorithm-property-ipworkspgp_openpgp-class) for additional details. **UseMemoryMode**: Determines whether the entire message is loaded into memory prior to encryption or decryption.This config determines whether the entire message is loaded into memory prior to encryption or decryption. By default, this config is *False*, and messages will be encrypted or decrypted in a stream-based manner. When *True*, the entire message will be loaded into memory prior to encryption or decryption. **UsePlatformAES**: Whether to use the platform AES implementation.By default class will use an internal implementation to perform AES. This is more self-contained and managed. In certain scenarios it may be better to use the platform's implementation. Set this to true to perform AES using the platform implementation. This is only available on Unix. The default is false. **VerifyClearTextSignatureWithCache**: Whether the cleartext message is cached in memory when verifying a cleartext signature.When verifying a cleartext signature, this configuration setting determines whether the cleartext message is cached in memory. This config is *True* by default, and **must** be true when verifying an OpenPGP v6 cleartext signature. When enabled, the cleartext portion will be cached in memory until the signature is fully processed. NOTE: If the signature is known to be an OpenPGP v4 cleartext signature beforehand (i.e., signed with a v4 key), this config may be set to *False*. However, if this config is disabled, the class will be unable to verify OpenPGP v6 cleartext signatures. In this case, the class will throw an exception when calling [VerifySignature](#verifysignature-method-ipworkspgp_openpgp-class) or [DecryptAndVerifySignature](#decryptandverifysignature-method-ipworkspgp_openpgp-class). **VersionHeader**: The Version header value in the ASCII armored OpenPGP message.This setting specifies the Version header value included in the ASCII armored OpenPGP message. This may be set before calling [Encrypt](#encrypt-method-ipworkspgp_openpgp-class), [Sign](#sign-method-ipworkspgp_openpgp-class), or [SignAndEncrypt](#signandencrypt-method-ipworkspgp_openpgp-class). The default value is "IPWorks PGP 2026". This setting will be populated after calling [Decrypt](#decrypt-method-ipworkspgp_openpgp-class), [VerifySignature](#verifysignature-method-ipworkspgp_openpgp-class), or [DecryptAndVerifySignature](#decryptandverifysignature-method-ipworkspgp_openpgp-class). **WriteToProgressEvent**: Whether to write output data so it is accessible from inside the progress event.When set to True this setting allows output data to be obtained from within the [Progress](#progress-event-ipworkspgp_openpgp-class) event. The class will repeatedly fire the [Progress](#progress-event-ipworkspgp_openpgp-class) event to provide output data. Inside the event check [OutputMessage](#outputmessage-property-ipworkspgp_openpgp-class) when the *Operation* parameter of the event is 2 (Write). The *IsEOF* parameter should be checked inside the event to determine when all output data has been provided. This allows output data to be chunked and obtained piece by piece. The default value is False. ### Base Config Settings **BuildInfo**: Information about the product's build.When queried, this setting will return a string containing information about the product's build. **CodePage**: The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001). The following is a list of valid code page identifiers: | | | | --- | --- | | Identifier | Name | | 037 | IBM EBCDIC - U.S./Canada | | 437 | OEM - United States | | 500 | IBM EBCDIC - International | | 708 | Arabic -

It will return the following information: - Product: The product the license is for. - Product Key: The key the license was generated from. - License Source: Where the license was found (e.g., RuntimeLicense, License File). - License Type: The type of license installed (e.g., Royalty Free, Single Server). - Last Valid Build: The last valid build number for which the license will work. **MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*. **ProcessIdleEvents**: Whether the class uses its internal event loop to process events when the main thread is idle.If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True. **SelectWaitMillis**: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20. **UseFIPSCompliantAPI**: Tells the class whether or not to use FIPS certified APIs.When set to *true*, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries. FIPS mode can be enabled by setting the *UseFIPSCompliantAPI* configuration setting to *true*. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior. For more details, please see the [FIPS 140-2 Compliance](https://www.nsoftware.com/kb/articles/fips.rst) article. NOTE: This setting is applicable only on Windows. NOTE: Enabling FIPS compliance requires a special license; please contact [sales@nsoftware.com](mailto:sales@nsoftware.com) for details. **UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the class will use the system security libraries by default to perform cryptographic functions where applicable. Setting this configuration setting to *true* tells the class to use the internal implementation instead of using the system security libraries. On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default. To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section. # Trappable Errors ([OpenPGP](#openpgp-class) Class) ### OpenPGP Errors | | | | --- | --- | | 101 | Cannot decode ASCII Armor data. | | 102 | Unknown ASCII Armor data type. | | 103 | Checksum failed. | | 104 | Unknown ASCII Armor header. | | 105 | Cannot decode PGP packet. | | 106 | Cannot encode PGP packet. | | 107 | Unknown PGP packet tag. | | 108 | Unsupported version. | | 109 | Unsupported algorithm. | | 110 | Unknown subpacket. | | 111 | Internal error. | | 112 | Feature not supported. | | 113 | Secret data was not encrypted. | | 114 | Cannot find the key. | | 115 | Error reading file. | | 116 | Error writing file. | | 117 | Error reading key. | | 118 | Error writing key. | | 119 | Cannot verify signature. | | 120 | Cannot create signature. | | 121 | Invalid UserId. | | 122 | Invalid passphrase. | | 123 | Data encryption failed. | | 124 | Error creating key. | | 125 | Unsupported symmetric algorithm. | | 126 | Unsupported hash. | | 127 | Unsupported compression algorithm. | | 128 | Invalid key usage. | | 129 | Component is busy. | | 130 | Error decrypting data. | | 131 | Data is not compressed. | | 132 | Error decompressing data. | | 133 | Error compressing data. | | 134 | Unsupported signature. | | 135 | Failed to overwrite file. | | 141 | No input. | | 142 | Signing was required, but the message was not signed. | | 143 | Encryption was required, but the message was not encrypted. | | 146 | No data integrity packet was found (MDC), but one was required. | | 200 | Out of memory. |
