Parameters

pSrc

Pointer to the input plaintext data stream of a variable length.

pDst

Pointer to the resulting ciphertext data stream.

len

Length of the plaintext and ciphertext data stream in bytes.

pState

Pointer to the IppsAES_GCMState context.

Description

The function encrypts the input data stream of a variable length according to GCM as specified in [NIST SP 800-38D].
