Go to the source code of this file.

## Enumerations
enum | DSASignatureFormat { DSA_P1363, DSA_DER, DSA_OPENPGP }
## Functions
unsigned int | DSAConvertSignatureFormat (byte *buffer, unsigned int bufferSize, DSASignatureFormat toFormat, const byte *signature, unsigned int signatureLen, DSASignatureFormat fromFormat)
| This function converts between these formats, and returns length of signature in the target format.

## Enumeration Type Documentation

enum DSASignatureFormat

| The DSA signature format used by Crypto++ is as defined by IEEE P1363. Java uses the DER format, and OpenPGP uses the OpenPGP format. Definition at line 13 of file dsa.h.

## Function Documentation

unsigned int DSAConvertSignatureFormat | ( | byte * | buffer,
|  | unsigned int | bufferSize,
|  | DSASignatureFormat | toFormat,
|  | const byte * | signature,
|  | unsigned int | 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() Definition at line 12 of file dsa.cpp.
