Я получаю эту ошибку:
org.bouncycastle.crypto.InvalidCipherTextException: pad block corrupted
at org.bouncycastle.crypto.paddings.PKCS7Padding.padCount(Unknown Source)
at org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher.doFinal(Unknown Source)
Вот мой код:
public byte[] process(byte[] input, BufferedBlockCipher bufferedBlockCipher, CipherParameters cipherParameters, boolean forEncryption) throws InvalidCipherTextException {
bufferedBlockCipher.init(forEncryption, cipherParameters);
int inputOffset = 0;
int inputLength = input.length;
int maximumOutputLength = bufferedBlockCipher.getOutputSize(inputLength);
byte[] output = new byte[maximumOutputLength];
int outputOffset = 0;
int outputLength = 0;
int bytesProcessed;
bytesProcessed = bufferedBlockCipher.processBytes(
input, inputOffset, inputLength,
output, outputOffset
);
outputOffset += bytesProcessed;
outputLength += bytesProcessed;
bytesProcessed = bufferedBlockCipher.doFinal(output, outputOffset);
outputOffset += bytesProcessed;
outputLength += bytesProcessed;
if (outputLength == output.length) {
return output;
} else {
byte[] truncatedOutput = new byte[outputLength];
System.arraycopy(
output, 0,
truncatedOutput, 0,
outputLength
);
return truncatedOutput;
}
}
