Method Summary

Modifier and Type	Method and Description
pack-priv int	doFinalInternal(byte[] output, int outputOffset, int maximumLen) Implements abstract org.conscrypt.OpenSSLCipher.doFinalInternal. API-specific implementation of the final block.
pack-priv void	engineInitInternal(byte[] encodedKey, AlgorithmParameterSpec params, SecureRandom random) Implements abstract org.conscrypt.OpenSSLCipher.engineInitInternal. API-specific implementation of initializing the cipher.
pack-priv abstract String	getCipherName(int keySize, OpenSSLCipher.Mode mode) Returns the OpenSSL cipher name for the particular `keySize` and cipher `mode`.
pack-priv int	getOutputSizeForFinal(int inputLen) Implements abstract org.conscrypt.OpenSSLCipher.getOutputSizeForFinal. The size of output if `doFinal()` is called with this `inputLen`.
pack-priv int	getOutputSizeForUpdate(int inputLen) Implements abstract org.conscrypt.OpenSSLCipher.getOutputSizeForUpdate. The size of output if `update()` is called with this `inputLen`.
private void	reset() Reset this Cipher instance state to process a new chunk of data.
pack-priv int	updateInternal(byte[] input, int inputOffset, int inputLen, byte[] output, int outputOffset, int maximumLen) Implements abstract org.conscrypt.OpenSSLCipher.updateInternal. API-specific implementation of updating the cipher.

calledUpdate	back to summary
private boolean calledUpdate Whether the cipher has processed any data yet. EVP_CIPHER doesn't like calling "doFinal()" in decryption mode without processing any updates.

cipherCtx	back to summary
private final NativeRef.EVP_CIPHER_CTX cipherCtx Native pointer for the OpenSSL EVP_CIPHER context.

modeBlockSize	back to summary
private int modeBlockSize The block size of the current mode.

Doc from org.conscrypt.OpenSSLCipher.doFinalInternal. API-specific implementation of the final block. The `maximumLen` will be the maximum length of the possible output as returned by `getOutputSizeForFinal(int)`. The return value must be the number of bytes processed and placed into `output`. On error, an exception must be thrown. Annotations @Override
