Method Detail

decryptback to summary
public void decrypt(byte[] bytes, int off, int len)

Implements org.h2.security.BlockCipher.decrypt.

Doc from org.h2.security.BlockCipher.decrypt.

Decrypt a number of bytes. This is done in-place, that means the bytes are overwritten.

Parameters
bytes:byte[]

the byte array

off:int

the start index

len:int

the number of bytes to decrypt
