aes192GcmEncrypt is GCM encryption mode with AES-192 single block cipher.
The algorithm reference is : “IEEE Standard for Authenticated Encryption with Length Expansion for Storage Devices” The implementation is modified for better performance.
Parameters:
payloadStrm | Input block stream text to be encrypted. |
cipherkeyStrm | Input cipher key used in encryption. |
IVStrm | Initialization vector stream. |
AADStrm | Additional authenticated data stream. |
lenAADStrm | Length of additional authenticated data in bits. |
lenPldStrm | Length of payload in bits. |
endLenStrm | Flag to signal the end of the length streams. |
cipherStrm | Output encrypted block stream text. |
lenCphStrm | Length of cipher in bits. |
tagStrm | The MAC stream. |
endTagStrm | Flag to signal the end of the MAC stream. |
