Reference

Properties

CipherMode As Long read/write

The AES cipher mode:
0 = CBC (Cipher Block Chaining). This is the default.
1 = ECB (Electronic Cookbook).
CBC is more secure, while ECB is higher-performance.
[top]

InitVector As Variant read/write

Should be set to a byte array of exactly 16 bytes. If unset, the IV is effectively all 0's. Both the encryptor and decryptor must use the same initialization vector for decryption to be successful. [top]

KeyLength As Long read/write

Determines the size in bits of the secret key, and can be 128, 192, or 256..[top]

PaddingScheme As Long read/write

The AES (Rijndael) encryption algorithm pads encrypted data to a multiple of 16 bytes. This determines what padding scheme is used. Possible values are:
0 = RFC 1423 padding scheme: Each padding byte is set to the number of padding bytes. If the data is already a multiple of 16 bytes, 16 additional bytes are added, each having the value 0x10. (This is the default padding scheme)
1 = FIPS81 (Federal Information Processing Standards 81) where the last byte contains the number of padding bytes, including itself, and the other padding bytes are set to random values.
2 = Each padding byte is set to a random value. The decryptor must know how many bytes are in the original unencrypted data.
[top]

PassPhrase As String read/write

Setting the PassPhrase also sets the SecretKey property according to the current value of the PassPhraseAlg. The PassPhrase property does not need to be set if the SecretKey is directly set by the application.[top]

PassPhraseAlg As Long read/write

This selects the Pass-Phrase-To-Secret-Key algorithm. Currently, the only possible value is 0 to provide compatibility with the Chilkat Crypt ActiveX Component. Additional conversions will be added on an as-needed basis in the future.[top]

SecretKey As Variant read/write

A byte array of exactly 16, 24, or 32 bytes depending on whether the KeyLength is 128, 192, or 256 bits.[top]

Version As String read-only

The version of the component such as "1.0.0".[top]

Methods

Decrypt( data As Variant ) As Variant

Decrypts data using the Rijndael (AES) encryption algorithm according to all the property settings. If the settings are not the same as used with encryption, the data returned will be garbled binary data.[top]

 

Encrypt( encryptedData As Variant ) As Variant

Encrypts data using the Rijndael (AES) encryption algorithm according to all the property settings.[top]

BZip2( data As Variant ) As Variant

Compresses data using the BZip2 compression algorithm. [top]

BUnzip2( compressedData As Variant ) As Variant

Decompresses data that was previously compressed by calling BZip2.[top]

Haval( data As Variant, bitLength as Long ) As Variant

Computes a 1-way hash using the HAVAL algorithm. The bitLength can be specified to be 128, 160, 192, 224, or 256 bits, and this is the number of bits in the output byte array. [top]

Md2( data As Variant ) As Variant

Computes a 1-way hash using the MD2 algorithm. The output is a byte array of exactly 128 bits (16 bytes).[top]

Md5( data As Variant ) As Variant

Computes a 1-way hash using the MD5 algorithm. The output is a byte array of exactly 128 bits (16 bytes)[top]

Sha160( data As Variant ) As Variant

Computes a 1-way hash using the SHA160 (also known as SHA-1) algorithm. The output is a byte array of exactly 160 bits (20 bytes)[top]

Sha256( data As Variant ) As Variant

Computes a 1-way hash using the SHA256 algorithm. The output is a byte array of exactly 256 bits (32 bytes)[top]

Sha384( data As Variant ) As Variant

Computes a 1-way hash using the SHA384 algorithm. The output is a byte array of exactly 384 bits (48 bytes)[top]

Sha512( data As Variant ) As Variant

Computes a 1-way hash using the SHA512 algorithm. The output is a byte array of exactly 512 bits (64 bytes) [top]

DecodeFromBase64( str As String ) As Variant

Decodes from a Base64 string to the original data.[top]

DecodeFromHex( str As String ) As Variant

Decodes from a hexidecimal string to the original data.[top]

DecodeFromQP( str As String ) As Variant

Decodes from a quoted-printable string to the original data. [top]

EncodeToBase64( data As Variant ) As String

Converts any kind of data (binary or text) to a Base64 string. [top]

EncodeToHex( data As Variant ) As String

Converts any kind of data (binary or text) to a hexidecimal string. [top]

EncodeToQP( data As Variant ) As String

Converts any kind of data (binary or text) to a quoted-printable string. [top]

 

IsUnlocked( ) As Long

Returns 1 if the component has already been unlocked, otherwise returns 0.[top]

UnlockComponent( unlockCode As String )

Unlocks the component. This must be called once before any other method, and will accept either a 30-day unlock code or a permanent (purchased) code. [top]
