DecryptBlock Method

Decrypts a block and returns the decrypted data.

Syntax

ezcrypt.decryptBlock(inputBuffer_Buffer, lastBlock, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err, buffer){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'buffer' is the value returned by the method.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method will decrypt the specified block and return the decrypted data.

InputBuffer specifies the encrypted block to decrypt.

LastBlock indicates whether the block is the last block.
