Examples with ECDSASignature org.tron.common.crypto.ECKey.ECDSASignature used on opensource projects

Example 1 with ECDSASignature

use of org.tron.common.crypto.ECKey.ECDSASignature in project java-tron by tronprotocol.

the class BlockCapsule method sign.

public void sign(byte[] privateKey) {
    // TODO private_key == null
    ECKey ecKey = ECKey.fromPrivate(privateKey);
    ECDSASignature signature = ecKey.sign(getRawHash().getBytes());
    ByteString sig = ByteString.copyFrom(signature.toBase64().getBytes());
    BlockHeader blockHeader = this.block.getBlockHeader().toBuilder().setWitnessSignature(sig).build();
    this.block = this.block.toBuilder().setBlockHeader(blockHeader).build();
}

Example 2 with ECDSASignature

use of org.tron.common.crypto.ECKey.ECDSASignature in project java-tron by tronprotocol.

the class TransactionCapsule method getBase64FromByteString.

public static String getBase64FromByteString(ByteString sign) {
    byte[] r = sign.substring(0, 32).toByteArray();
    byte[] s = sign.substring(32, 64).toByteArray();
    byte v = sign.byteAt(64);
    if (v < 27) {
        // revId -> v
        v += 27;
    }
    ECDSASignature signature = ECDSASignature.fromComponents(r, s, v);
    return signature.toBase64();
}
