Syntax

TipcAES

Remarks

The AES component can be used to encrypt and decrypt data through Advanced Encryption Standard (AES) cryptography. Includes support for AES 128, 192, and 256 bit keys.

To begin simply specify the data you wish to encrypt or decrypt.

Input and Output Properties

The component 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:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Before encrypting you must have a valid Key and IV. There are a few options available to you in regards to key management. The easiest option is to simply set KeyPassword. When KeyPassword is set the component will automatically create a Key and IV using the PKCS5 password digest algorithm. This means there is only one value you need to keep track of.

If you wish to have more control over the Key and IV values you may specify the properties yourself. If IV is left empty, one will be created for you when you call Encrypt or Decrypt.

A simple example: Component.InputFile = "C:\MyFile.txt"; Component.OutputFile = "C:\Encrypted.txt"; Component.KeyPassword = "password"; Component.Encrypt();

Note that by default the component uses a key size of 256. You may specify the key size (such as 128 or 192) by setting KeySize.

CipherMode Property (AES Component)

The cipher mode of operation.

Syntax

property CipherMode: TipcTAESCipherModes read get_CipherMode write set_CipherMode;

TipcTAESCipherModes = (
  acmCBC,
  acmECB,
  acmOFB,
  acmCFB,
  acmCTS,
  acm8OFB,
  acmGCM,
  acm8CFB,
  acmCTR,
  acmXTS
);

Default Value

acmCBC

Remarks

The cipher mode of operation.

Possible values are:

0 (cmCBC - default) The Cipher Block Chaining (CBC) is a mode of operation for a block cipher, one in which a sequence of bits is encrypted as a single unit or block with a cipher key applied to the entire block.
1 (cmECB) The Electronic Codebook (ECB) mode encrypts each block separately. Important: It is not recommend to use this model when encrypting more than one block because it may introduce security risks.
2 (cmOFB) The Output Feedback (n-bit, NOFB) mode makes a block cipher into a synchronous stream cipher. It has some similarities to CFB mode in that it permits encryption of differing block sizes, but has the key difference that the output of the encryption block function is the feedback (instead of the ciphertext).
3 (cmCFB) The Cipher Feedback (CFB) mode processes a small amount of incremental text into ciphertext, rather than processing a whole block at one time.
4 (cmCTS) The Cipher Text Stealing (CTS) mode handles any length of plain text and produces cipher text whose length matches the plain text length. This mode behaves like the CBC mode for all but the last two blocks of the plain text.
5 (cm8OFB) 8-bit Output Feedback (OFB) cipher mode.
7 (cm8CFB) 8-bit Cipher Feedback (CFB) cipher mode.
6 (acmGCM) Galois/Counter (GCM) cipher mode.
8 (acmCTR) Counter (CTR) cipher mode.
9 (acmXTS) XEX Tweakable Block Cipher with Ciphertext Stealing (XTS) cipher mode.
GCM Notes

When setting this value to 6 (acmGCM) the following settings are also applicable:

GCM mode code example: //Encrypt aes.CipherMode = AesCipherModes.acmGCM; aes.KeyPassword = "test"; aes.InputMessage = "input data"; aes.Config("AdditionalData=" + hex_aad); //Optional aes.Encrypt(); string authTag = aes.Config("AuthTag"); byte[] outputMessage = aes.OutputMessageB; //Decrypt aes.CipherMode = AesCipherModes.acmGCM; aes.KeyPassword = "test"; aes.InputMessageB = outputMessage; aes.Config("AdditionalData=" + hex_aa); aes.Config("AuthenticationTag=" + authTag); aes.Decrypt(); XTS Notes

When setting this value to 9 (acmXTS) the following settings are also applicable:

PaddingMode has no effect when using acmXTS -- the InputMessage MUST be a multiple of XTSDataUnitLength.

Syntax

property KeyPassword: String read get_KeyPassword write set_KeyPassword;

Default Value

''

Remarks

When this property is set the component will calculate values for Key and IV using the PKCS5 password digest algorithm. This provides a simpler alternative to creating and managing Key and IV values directly.

The size of the Key generated is dependent on the value of KeySize.

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

This property is read-only and not available at design time.

Overwrite Property (AES Component)

Indicates whether or not the component should overwrite files.

Syntax

property Overwrite: Boolean read get_Overwrite write set_Overwrite;

Default Value

false

Remarks

This property indicates whether or not the component will overwrite OutputFile. If Overwrite is False, an error will be thrown whenever OutputFile exists before an operation. The default value is False.

PaddingMode Property (AES Component)

The padding mode.

Syntax

property PaddingMode: TipcTPaddingModes read get_PaddingMode write set_PaddingMode;

TipcTPaddingModes = (
  pmPKCS7,
  pmZeros,
  pmNone,
  pmANSIX923,
  pmISO10126
);

Default Value

pmPKCS7

Remarks

PaddingMode is used to pad the final input block to guarantee that it is the correct size required for the selected CipherMode. If the input size is a multiple of the cipher's BlockSize, an extra block of padding will be appended to the input. This enables the decrypting agent to know with certainty how many bytes of padding are included. Each mode pads the data differently. Possible values are:

0 (pmPKCS7 - default) The data is padded with a series of bytes that are each equal to the number of bytes used. For instance, in the example below the data must be padded with 3 additional bytes, so each byte value will be 3.

Raw Data: AA AA AA AA AA

PKCS7 Padded Data: AA AA AA AA AA 03 03 03

1 (pmZeros) The data is padded with null bytes.
2 (pmNone) No padding will be performed.
3 (pmANSIX923) The ANSIX923 padding string consists of a sequence of bytes filled with zeros before the length. For instance, in the example below the data must be padded with 3 additional bytes, so last byte value will be 3.

Raw Data: AA AA AA AA AA

ANSIX923 padding Data: AA AA AA AA AA 00 00 03

4 (pmISO10126) The ISO10126 padding string consists of random data before the length. For instance, in the example below the data must be padded with 3 additional bytes, so last byte value will be 3.

Raw Data: AA AA AA AA AA

ISO10126 padding Data: AA AA AA AA AA F8 EF 03

When calling Decrypt the PaddingMode must match the value used when the data was encrypted.

Note: When using a value of 2 (pmNone), unless the length of input is an exact multiple of the cipher's input BlockSize, the final block of plaintext may be lost.

UseHex Property (AES Component)

Whether input or output is hex encoded.

Syntax

property UseHex: Boolean read get_UseHex write set_UseHex;

Default Value

false

Remarks

This property specifies whether the encrypted data is hex encoded.

If set to True, when Encrypt is called the component will perform the encryption as normal and then hex encode the output. OutputMessage or OutputFile will hold hex encoded data.

If set to True, when Decrypt is called the component will expect InputMessage or InputFile to hold hex encoded data. The component will then hex decode the data and perform decryption as normal.

Config Method (AES Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

The BytesProcessed parameter holds the total number of bytes processed so far.

Config Settings (AES Component)

The component 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 component, access to these internal properties is provided through the Config method.

AES Config Settings

AdditionalAuthData:   Additional authentication data (AAD) used in GCM mode.

This setting optionally specifies additional authentication data. The data specified must be hex encoded. This is only applicable when CipherMode is set to 6 (cmGCM). This may be set prior to calling Encrypt or Decrypt. Note that the AAD is authenticated but not encrypted, so it is not included in OutputMessage

AuthTag:   The authentication tag used in GCM mode.

This setting is only applicable when CipherMode is set to 6 (cmGCM). This is populated with a hex encoded value after calling Encrypt. It must be specified with a hex encoded value before calling Decrypt.

AuthTagLength:   The authentication tag length used in GCM mode.

This setting is only applicable when CipherMode is set to 6 (cmGCM). This may be set before calling Encrypt. It may also be set before calling Decrypt, but is not required. The default value is 128. Valid values are

  • 0*
  • 96
  • 104
  • 112
  • 120
  • 128 (default)
* May be set to 0 when calling Decrypt only. In this case no value needs to be passed to AuthTag. Be aware that this is a security risk as the ciphertext will not be authenticated. If it was tampered with there would be no indication. NIST Special Publication 800-38D forbids implementations from validating or generating messages without an authentication tag, but this functionality can be useful in certain real-world scenarios.
BlockSize:   The block size, in bits, of the cryptographic operation.

The block size is a basic data unit in the operation of encrypt or decrypt. Messages longer than the block size are seen as successive blocks. If the message is shorter than the block size, the message will be padded with extra bits to reach the block size according to PaddingMode. Different symmetric algorithm has different valid block sizes.

The following algorithms have a fixed block size: AES, CAST, DES, IDEA, RC2, TripleDES, Blowfish, and Twofish.

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.

EncryptedDataEncoding:   The encoding of the encrypted input or output data.

This configuration setting specifies how the encrypted data is encoded (if at all).

When Encrypt is called the component will perform the encryption as normal and then encode the output as specified here. OutputMessage or OutputFile will hold the encoded data.

When Decrypt is called the component will expect InputMessage or InputFile to hold the encoded data as specified here. The component will then decode the data and perform decryption as normal.

Possible values are:

  • 0 (none - default)
  • 1 (Base64)
  • 2 (Hex)
  • 3 (Base64URL)

IncludeAuthTag:   Whether to append the authentication tag to the cipher text in GCM mode.

This setting controls whether AuthTag is appended to the cipher text. This may be useful in cases where the other party knows to look for the authentication tag at the end of the data. The default value is False.

IncludeIV:   Whether to prepend the IV to the output data and read the IV from the input data.

If this config is true, the IV will be automatically prepended to the output data when calling Encrypt. When calling Decrypt and this setting is True, the IV is automatically extracted form the ciphertext. The default value is False.

KeyPasswordAlgorithm:   The hash algorithm used to derive the Key and IV from the KeyPassword property.

This configuration setting specifies which hash algorithm will be used when deriving the Key and IV from KeyPassword. The default value is "MD5". Possible values are:

  • "SHA1"
  • "MD2"
  • "MD5" (default)
  • "HMAC-SHA1"
  • "HMAC-SHA224"
  • "HMAC-SHA256"
  • "HMAC-SHA384"
  • "HMAC-SHA512"
  • "HMAC-MD5"
  • "HMAC-RIPEMD160"

When using any HMAC algorithm the PBKDF#2 method from RFC 2898 is used. Any other algorithm uses PBKDF#1 from the same RFC.

KeyPasswordIterations:   The number of iterations performed when using KeyPassword to derive the Key and IV.

This configuration setting specifies the number of iterations performed when using KeyPassword to calculate values for Key and IV. When using PBKDF#2 the default number of iterations is 10,000. When using PBKDF#1 the default number is 10.

KeyPasswordSalt:   The salt value used in conjunction with the KeyPassword to derive the Key and IV.

This configuration setting specifies the hex encoded salt value to be used along with the KeyPassword when calculating values for Key and IV.

KeySize:   The size, in bits, of secret key for the symmetric algorithm.

The legal key sizes vary depending on the algorithm. The KeySize and BlockSize configuration settings may be set to specify the key and block size (in bits).

This setting is only applicable when KeyPassword is specified.

Note that when using the EzCrypt component, KeySize should be set after setting the Algorithm property.

UsePlatformAES:   Whether to use the platform AES implementation.

This setting controls whether the component uses it's own AES implementation or the current platform's implementation. Using the platform implementation is only supported on Windows.

XTSDataUnitLength:   The length of the XTS data unit.

When CipherMode is acmXTS, set this to the length of the XTS data unit in bytes. The default value is 512.

XTSInitialTweak:   The initial XTS tweak value.

Set this to the initial tweak value when CipherMode is acmXTS. This can be set to either a decimal or hexadecimal number representing the value. The default value is 0. Here are two examples: aes.Config("XTSInitialTweak=6700"); // Decimal aes.Config("XTSInitialTweak=C1DD77FDGA"); // Hexadecimal

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).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. 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.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseFIPSCompliantAPI:   Tells the component whether or not to use FIPS certified APIs.

When set to True, the component 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 components 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 article.

Note: This setting is applicable only on Windows.

Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to False, the component will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to True tells the component to use the internal implementation instead of using the system security libraries.

This setting is set to False by default on all platforms.
