    const TArrayView< uint8 > OutCiphertext,
    int32 & OutCiphertextBytesWritten
)

Remarks

Encrypt one or more blocks of data. OutCiphertext must be at least size of the result of GetUpdateBufferSizeBytes, or it will fail. If Plaintext is less than the size of a block, OutCiphertext may or may not be modified until more data is provided in a future call to Update.

Returns

Success if all input was valid and was encrypted successfully, or Failure otherwise

Parameters

Parameter	Description
Plaintext	The Data to be encrypted and placed into OutCiphertext
OutCiphertext	The encrypted output of Plaintext. May not be written to if Plaintext is less than block size. Must be at least GetUpdateBufferSizeBytes in size or the call will fail
OutCiphertextBytesWritten	The amount of data that was written. This can be from 0 to (size of plaintext + blocksize - 1).
