They decrypt a public key encrypted symmetric key and +then decrypt data using it. + +EVP_OpenInit() initializes a cipher context B for decryption +with cipher B. It decrypts the encrypted symmetric key of length +B bytes passed in the B parameter using the private key B. +The IV is supplied in the B parameter. + +EVP_OpenUpdate() and EVP_OpenFinal() have exactly the same properties +as the EVP_DecryptUpdate() and EVP_DecryptFinal() routines, as +documented on the L manual +page. + +=head1 NOTES + +It is possible to call EVP_OpenInit() twice in the same way as +EVP_DecryptInit(). The first call should have B set to NULL +and (after setting any cipher parameters) it should be called again +with B set to NULL. + +If the cipher passed in the B parameter is a variable length +cipher then the key length will be set to the value of the recovered +key length. If the cipher is a fixed length cipher then the recovered +key length must match the fixed cipher length. + +=head1 RETURN VALUES + +EVP_OpenInit() returns 0 on error or a non zero integer (actually the +recovered secret key size) if successful. + +EVP_OpenUpdate() returns 1 for success or 0 for failure. + +EVP_OpenFinal() returns 0 if the decrypt failed or 1 for success. + +=head1 SEE ALSO + +L, L, +L, +L + +=head1 HISTORY + +=cut -- cgit v1.2.3
