ParagonIE_Sodium_Compat::crypto_aead_aes256gcm_decrypt() public WP 1.0

Authenticated Encryption with Associated Data: Decryption



This mode uses a 64-bit random nonce with a 64-bit counter. IETF mode uses a 96-bit random nonce with a 32-bit counter.

Это метод класса: ParagonIE_Sodium_Compat{}

Хуков нет.
