Method Summary

Modifier and Type	Method and Description
private CipherParameters	adjustParameters(AlgorithmParameterSpec params, CipherParameters param)
protected byte[]	engineDoFinal(byte[] the input buffer input, int the offset in `input` where the input starts inputOffset, int the input length inputLen) Overrides org.bouncycastle.jcajce.provider.symmetric.util.BaseWrapCipher.engineDoFinal. Encrypts or decrypts data in a single-part operation, or finishes a multiple-part operation.
protected int	engineDoFinal(byte[] the input buffer input, int the offset in `input` where the input starts inputOffset, int the input length inputLen, byte[] the buffer for the result output, int the offset in `output` where the result is stored outputOffset) Overrides org.bouncycastle.jcajce.provider.symmetric.util.BaseWrapCipher.engineDoFinal. Encrypts or decrypts data in a single-part operation, or finishes a multiple-part operation.
protected int	engineGetBlockSize() Overrides org.bouncycastle.jcajce.provider.symmetric.util.BaseWrapCipher.engineGetBlockSize. Returns the block size (in bytes).
protected byte[]	engineGetIV() Overrides org.bouncycastle.jcajce.provider.symmetric.util.BaseWrapCipher.engineGetIV. Returns the initialization vector (IV) in a new buffer.
protected int	engineGetKeySize(Key the key object key) Overrides org.bouncycastle.jcajce.provider.symmetric.util.BaseWrapCipher.engineGetKeySize. Returns the key size of the given key object in bits.
protected int	engineGetOutputSize(int the input length (in bytes) inputLen) Overrides org.bouncycastle.jcajce.provider.symmetric.util.BaseWrapCipher.engineGetOutputSize. Returns the length in bytes that an output buffer would need to be in order to hold the result of the next `update` or `doFinal` operation, given the input length `inputLen` (in bytes).
protected AlgorithmParameters	engineGetParameters() Overrides org.bouncycastle.jcajce.provider.symmetric.util.BaseWrapCipher.engineGetParameters. Returns the parameters used with this cipher.
