OpenPGPBlackbox package

OpenPGPBlackbox includes the components and functions, related to OpenPGP technology. With OpenPGPBlackbox you can encrypt, sign, compress, decrypt, verify and decompress the data using OpenPGP standard.

For OpenPGP key management OpenPGPBlackbox includes the components and functions, that let you generate, sign, revoke the OpenPGP keys and maintain OpenPGP keyrings.

OpenPGPBlackbox includes the following components:

Component name Summary TElPGPReader This component provides functionality for PGP message parsing. It allows to decrypt, decompress, verify signatures, and return "clear", unsecured data. TElPGPWriter Provides functionality for encrypting/signing/armoring/compressing data according to Open PGP standard. TElPGPWriter lets you avoid dealing with individual streams' parameters an intermediate data blocks. TElPGPKeyring This class is used to hold and access the PGP keys. TElPGPPublicKey Represents a PGP public key. TElPGPSecretKey Represents a PGP secret key.

Supplementary classes included into OpenPGPBlackbox are

Class name Summary PGP Keys TElPGPCustomPublicKey The base class for PGP public key/subkey. TElPGPCustomSecretKey The base class for PGP secret key/subkey. TElPGPPublicSubkey Each TElPGPPublicKey can have several subkeys, represented by TElPGPPublicSubkey class. TElPGPSecretSubkey Each TElPGPSecretKey can have several subkeys, represented by instances of this class. TElPGPCustomUser The ancestor for the classes which describe PGP user. TElPGPSignature This class provides functionality to verify PGP signature. TElPGPTrust This class contains information about trust level of PGP entities. TElPGPJpegImage Stores photo in .jpeg format as binary data. This photo is used to identify a PGP user. PGP Streams TElPGPStream The base class for all PGP stream classes. TElPGPArmoringStream This class provides data stream armoring, i.e. encoding the data into Base64 representation with adding the headers and boundary. TElPGPDearmoringStream This class provides data stream dearmoring, i.e. removing the headers and boundary and decoding the data from Base64 representation. TElPGPCompressingStream This class allows file compression using zlib algorithm. TElPGPDecompressingStream This class provides functionality to decompress files. TElPGPEncryptingStream This class provides data encryption functionality. TElPGPDecryptingStream This class provides data decryption functionality. TElPGPEnvelopingStream This class provides functionality to make an envelope for a data (message). TElPGPUnenvelopingStream Removes an envelope from a file or data block. TElPGPSigningStream This class allows creation of clear-text signatures of text data. TElPGPClearTextVerifyingStream This class is allows verification of clear-text signatures. PGP Signature Subpackets TElPGPSignatureSubpacket The base class for other PGP signature subpackets classes. TElPGPCreationTimeSignatureSubpacket This subpacket contains the time when the signature was made. TElPGPExpirationTimeSignatureSubpacket This subpacket contains the time of signature expiration. TElPGPExportableCertificationSignatureSubpacket This subpacket specifies, whether the signature is exportable. TElPGPIssuerKeyIDSignatureSubpacket Contains the OpenPGP key ID of the key issuing the signature. TElPGPKeyExpirationTimeSignatureSubpacket Contains the validity period of a PGP key. TElPGPKeyFlagsSignatureSubpacket This subpacket contains a list of binary flags that hold information about a key. TElPGPKeyServerPreferencesSignatureSubpacket This signature subpacket contains a number of flags that indicate preferences that the key holder has about how the key is handled on a key server. TElPGPNotationDataSignatureSubpacket describes a "notation" on the signature that the issuer wishes to make. TElPGPPolicyURLSignatureSubpacket Contains a URL of the document describing signature policy. TElPGPPreferredCompressionAlgorithmsSignatureSubpacket Contains preferred compression algorithms of the key holder. TElPGPPreferredHashAlgorithmsSignatureSubpacket Contains preferred hash algorithms of the key holder. TElPGPPreferredKeyServerSignatureSubpacket Contains a URL of the key server that is preferred by key holder. TElPGPPreferredSymmetricAlgorithmsSignatureSubpacket Contains preferred symmetric algorithms of the key holder. TElPGPPrimaryUserIDSignatureSubpacket This subpacket contains flag in a user id's self signature that states whether this user id is the main user id for certain key. TElPGPReasonForRevocationSignatureSubpacket Contains a reason for key (certificate) revocation. TElPGPRegularExpressionSignatureSubpacket This subpacket is used in conjunction with TElPGPTrustSignatureSubpacket. TElPGPRevocableSignatureSubpacket Contains signature revocability status. TElPGPRevocationKeySignatureSubpacket Specifies revocation key for the certain key. TElPGPTrustSignatureSubpacket Contains trust level of the signature. TElPGPX509SignatureSubpacket This class is used for X.509 certificates storing. TElPGPSignersUserIDSignatureSubpacket Contains user id of the signer. Supplementary classes TElPGPUtilsX This class contains helper methods for data processing in PGP.
