Module AES.GCM

include AEAD
type key

The abstract type for the key.

val authenticate_encrypt : key:key -> nonce:Cstruct.t -> ?adata:Cstruct.t -> Cstruct.t -> Cstruct.t

authenticate_encrypt ~key ~nonce ~adata msg encrypts msg with key and nonce, and appends an authentication tag computed over the encrypted msg, using key, nonce, and adata.

val authenticate_decrypt : key:key -> nonce:Cstruct.t -> ?adata:Cstruct.t -> Cstruct.t -> Cstruct.t option

authenticate_decrypt ~key ~nonce ~adata msg splits msg into encrypted data and authentication tag, computes the authentication tag using key, nonce, and adata, and decrypts the encrypted data. If the authentication tags match, the decrypted data is returned.

val of_secret : Cstruct.t -> key

Construct the encryption key corresponding to secret.

val key_sizes : int array

Key sizes allowed with this cipher.

val block_size : int

The size of a single block.

val tag_size : int

The size of the authentication tag.
