cipherEncryptBytes

Encrypts data in a byte array using the specified block cipher algorithm, mode and padding. The key and initialization vector are passed as byte arrays.

Syntax

Public Function cipherEncryptBytes ( _
    lpInput() As Byte, _
    lpKey() As Byte, _
    lpIV() As Byte, _
    szAlgModePad As String, _
    Optional nOptions As Long = 0 _
) As Byte()

Parameters

lpInput

Input data to be encrypted.

lpKey

Key of exact length for block cipher algorithm.

lpIV

Initialization Vector (IV) of exactly the block size or empty array for ECB mode.

szAlgModePad

String with block cipher algorithm, mode and padding, e.g. "aes128/cbc/pkcs5"

Alg:  aes128|aes192|aes256|tdea|3des|desede3
Mode: ecb|cbc|ofb|cfb|ctr
Pad:  pkcs5|nopad|oneandzeroes|ansix923|w3c

nOptions

Add API_IV_PREFIX to prepend the IV before the ciphertext in the output (ignored for ECB mode).

Return Value
