5 | EVP_OpenInit, EVP_OpenUpdate, EVP_OpenFinal - EVP envelope decryption | ||
6 | |||
7 | =head1 SYNOPSIS | ||
8 | |||
9 | #include <openssl/evp.h> | ||
10 | |||
11 | int EVP_OpenInit(EVP_CIPHER_CTX *ctx,EVP_CIPHER *type,unsigned char *ek, | ||
12 | int ekl,unsigned char *iv,EVP_PKEY *priv); | ||
13 | void EVP_OpenUpdate(EVP_CIPHER_CTX *ctx, unsigned char *out, | ||
14 | int *outl, unsigned char *in, int inl); | ||
15 | void EVP_OpenFinal(EVP_CIPHER_CTX *ctx, unsigned char *out, | ||
16 | int *outl); | ||
17 | |||
18 | =head1 DESCRIPTION | ||
19 | |||
20 | The EVP envelope routines are a high level interface to envelope | ||
21 | decryption. They decrypt a public key encrypted symmetric key and | ||
22 | then decrypt data using it. | ||
23 | |||
24 | EVP_OpenInit() initialises a cipher context B<ctx> for decryption | ||
25 | with cipher B<type>. It decrypts the encrypted symmetric key of length | ||
26 | B<ekl> bytes passed in the B<ek> parameter using the private key B<priv>. | ||
27 | The IV is supplied in the B<iv> parameter. | ||
28 | |||
29 | EVP_OpenUpdate() and EVP_OpenFinal() have exactly the same properties | ||
30 | as the EVP_DecryptUpdate() and EVP_DecryptFinal() routines, as | ||
31 | documented on the L<EVP_EncryptInit(3)|EVP_EncryptInit(3)> manual | ||
32 | page. | ||
33 | |||
34 | =head1 RETURN VALUES | ||
35 | |||
36 | EVP_OpenInit() returns -1 on error or an non zero integer (actually the | ||
37 | recovered secret key size) if successful. | ||
38 | |||
39 | EVP_SealUpdate() does not return a value. | ||
40 | |||
41 | EVP_SealFinal() returns 0 if the decrypt failed or 1 for success. | ||
