the class StandardDSAEncoding method decode.

public BigInteger[] decode(BigInteger n, byte[] encoding) throws IOException {
    ASN1Sequence seq = (ASN1Sequence) ASN1Primitive.fromByteArray(encoding);
    if (seq.size() == 2) {
        BigInteger r = decodeValue(n, seq, 0);
        BigInteger s = decodeValue(n, seq, 1);
        byte[] expectedEncoding = encode(n, r, s);
        if (Arrays.areEqual(expectedEncoding, encoding)) {
            return new BigInteger[] { r, s };
        }
    }
    throw new IllegalArgumentException("Malformed signature");
