aeadUpdate

CryptoSys API Library Manual

aeadUpdate

Encrypts or decrypts a chunk of input (in incremental mode).

Syntax

[VBA]

Public Function aeadUpdate ( _
    hContext As Long, _
    lpData() As Byte _
) As Byte()

Parameters

hContext: Handle to the AEAD context set up by an earlier call to aeadInitKey.
lpData: Data to be encrypted or decrypted.

Return Value

Byte(): Encrypted or decrypted data in array of exactly the same length as input; or an empty array on error

Remarks

This function may be repeated to add data in chunks. The input data is encrypted or decrypted depending on the start mode set by a preceding call to aeadStartEncrypt or aeadStartDecrypt, respectively. It must eventually be followed by either aeadFinishEncrypt or aeadFinishDecrypt, which must match the start mode.
