Member Data Documentation

destroy

void(* openssl_encrypt_info::destroy) (struct openssl_encrypt *state)

Destroys state

Definition at line 77 of file openssl_encrypt.h.

encrypt

int(* openssl_encrypt_info::encrypt) (struct openssl_encrypt *encryption, char *plaintext, int plaintext_len, char *aad, int aad_len, char *ciphertext)

Encrypts a block of data

Parameters

[in]	encryption	state
[in]	plaintext	plain text
[in]	plaintext_len	length of plain text
[in]	aad	Additional Authenticated Data this won't be encrypted but passed in plaintext along ciphertext. These data are autheticated only if working in some AE mode
[in]	aad_len	length of AAD text
[out]	ciphertext	resulting ciphertext, can be up to (plaintext_len + MAX_CRYPTO_EXCEED) length

Returns

size of writen ciphertext

Return values

0

on error

get_overhead

int(* openssl_encrypt_info::get_overhead) (struct openssl_encrypt *encryption)

Returns maximal number of bytest that the ciphertext length may exceed plaintext for selected encryption.

Parameters

[in]

encryption

state

Returns

max overhead (must be <= MAX_CRYPTO_EXCEED)

init

int(* openssl_encrypt_info::init) (struct openssl_encrypt **state, const char *passphrase)

Initializes encryption

Parameters

[out]	state	created state
[in]	passphrase	key material (NULL-terminated)
[in]	mode

Return values

0	success
<0	failure
>0	state not created
