let 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 * int
let 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

The sizes of inbuf

On error, the method fails.
