Enumerations

enum  DSASignatureFormat { DSA_P1363, DSA_DER, DSA_OPENPGP }

Functions

size_t DSAConvertSignatureFormat (byte *buffer, size_t bufferSize, DSASignatureFormat toFormat, const byte *signature, size_t signatureLen, DSASignatureFormat fromFormat)
 This function converts between these formats, and returns length of signature in the target format.


Enumeration Type Documentation

The DSA signature format used by Crypto++ is as defined by IEEE P1363. Java uses the DER format, and OpenPGP uses the OpenPGP format.

Function Documentation

size_t DSAConvertSignatureFormat ( byte *  buffer,
size_t  bufferSize,
DSASignatureFormat  toFormat,
const byte *  signature,
size_t  signatureLen,
DSASignatureFormat  fromFormat 
)

This function converts between these formats, and returns length of signature in the target format.

If toFormat == DSA_P1363, bufferSize must equal publicKey.SignatureLength()
