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()
