This value doesn't take padding into account.
method supports_aead : boolmethod set_iv : string -> unitmethod set_header : string -> unitmethod encrypt : last:bool -> Netsys_types.memory -> Netsys_types.memory -> int * intlet n_in, n_out = encrypt ~last inbuf outbuf:
Encrypts the text in inbuf and
writes the result to outbuf. The returned numbers indicate how
much data was processed: the first n_in bytes of inbuf are
encrypted, and the first n_out bytes of outbuf are filled with
ciphertext.
This function can be called several
times to encrypt a larger text. last should be set for the last
call.
The sizes of inbuf and outbuf must be at least one block
in order to produce non-zero (n_in,n_out). (For `CTS only:
two blocks.)
method decrypt : last:bool -> Netsys_types.memory -> Netsys_types.memory -> int * intlet n_in, n_out = decrypt ~last inbuf outbuf:
Decrypts the text in inbuf and
writes the result to outbuf. The returned numbers indicate how
much data was processed: the first n_in bytes of inbuf are
decrypted, and the first n_out bytes of outbuf are filled with
plaintext.
This function can be called several
times to decrypt a larger text. last should be set for the last
call.
The sizes of inbuf and outbuf must be at least one block
in order to produce non-zero (n_in,n_out). (For `CTS only:
two blocks.)
On error, the method fails.
