Aes gcm

I am working on decrypting a string from a PHP OpenSSL implementation using AES GCM.

In working to decrypt it, it seems that there is some glue missing between cSecureSymmetricKeyEncryptionMethod.pkg:

Function NewDecryptor UChar[] ucaIV Returns Handle

In comparison to cCngAuthenticatedEncryption_Impl.pkg


Function NewDecryptor UChar[] ucaNonce UChar[] ucaAuthTag UChar[] ucaAAD Returns Handle

In the process, I am getting an error message:


D:\Dev\Memsys5\Programs\memtest.exe
Required message argument missing


Error: 57


GET_NEWDECRYPTOR (18237) - oObject (838) - at address 209176

MSG_COMMAND (648) - oDecrypt (766) - in native code

Was this deliberatly left out of cSecureSymmetricKeyEncryptionMethod.pkg, or is this an oversight?
