Public Methods
zx_status_t InitSeal (Algorithm aead, const Secret & key, const Bytes & iv)Sets up the AEAD to use the algorithm indicated by |aead| to encrypt data using the given
|key| and |iv|.
Defined at line 51 of file ../../src/security/lib/fcrypto/aead.h
zx_status_t InitOpen (Algorithm aead, const Secret & key, const Bytes & iv)Sets up the AEAD to use the algorithm indicated by |aead| to decrypt data using the given
|key| and |iv|.

void ~AEAD ()Defined at line 114 of file ../../src/security/lib/fcrypto/aead.cc
zx_status_t GetKeyLen (Algorithm aead, size_t * out)Gets the number of bytes needed for the symmetric key used by the given |aead|.
Defined at line 64 of file ../../src/security/lib/fcrypto/aead.cc
zx_status_t Seal (const Bytes & ptext, uint64_t * out_nonce, Bytes * out_ctext)Encrypts data from |ptext| to |ctext|, based on the parameters set in |InitSeal|. Saves the
|iv| used; |iv| will be resized and filled automatically. The AEAD tag is stored at the end
of |ctext| This method will fail if called 2^64 or more times with the same key and IV. The
second variant includes additional authenticated data in the tag calculation.

zx_status_t Seal (const Bytes & ptext, const Bytes & aad, uint64_t * out_nonce, Bytes * out_ctext)Defined at line 68 of file ../../src/security/lib/fcrypto/aead.h
zx_status_t Open (uint64_t nonce, const Bytes & ctext, Bytes * out_ptext)Decrypts data from |ctext| to |ptext|, based on the parameters set in |InitOpen|.
Decryption can only succeed if the |iv| matches those produced by |Seal| and the AEAD tag is
included in |ctext|. The second variant includes additional authenticated data in the tag
calculation.
