RSA Public-Key Encryption and Digital Signatures Made Easy

Reference

Properties

ErrorLogHtml As String read-only

Contains error messages for the last failed method call in HTML format with "<br>" line endings.
[top]

ErrorLogText As String read-only

Contains error messages for the last failed method call in plain-text format. [top]

ErrorLogXml As String read-only

Contains error messages for the last failed method call in XML format.[top]

LastAlgorithm As String read-only

The name of the last encryption algorithm used in an encrypt or decrypt operation. The encryption algorithm is implicitly chosen by the certificate and default Cryptographic Service Provider, unless a CSP is explicitly specified using SetCSP.
[top]

LastCertSubject As String read-only

The full subject-name of the last certificate used in for encryption, decryption, signing ofr signature verification.[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 a PKCS7 message, which is what the Encrypt method produces. The certificate with private key must be installed on the system in a place such that Internet Explorer or Outlook can find it, which means that Chilkat Easy RSA should also find it. [top]

 

Encrypt( encryptedData As Variant ) As Variant

Encrypts data using the certificate previously specified in a call to SetEncryptCert. The output of this method is a PKCS7 message that can be passed to the Decrypt method to restore the original data.[top]

SetEncryptCert( cert as ChilkatCert )

Sets the certificate to be used for encryption. This must be called before calling Encrypt. Refer to the Chilkat Certificate documentation for information on how to instantiate a certificate object. [top]

CreateSignature( encryptedData As Variant ) As Variant

Creates a detached digital signature using the certificate previously specified by calling SetSigningCert. The certificate and private key must reside on the system of the calling process.[top

SetSigningCert( cert as ChilkatCert )

Sets the certificate to be used for signing. This must be called before calling CreateSignature. Refer to the Chilkat Certificate documentation for information on how to instantiate a certificate object.[top]

VerifySignature( data As Variant, signature As Variant) As Long

Compares the data against the detached signature and returns 1 (true) if the signature is valid and the data is guaranteed to have not changed. Returns 0 (false) if the signature verification process failed, or if the data was altered.[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]

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]

SaveToXml( filename As String )

Saves the ErrorLogXml property to a file.[top]
