NAME
RSA_private_encrypt, RSA_public_decrypt — low level signature operationsSYNOPSIS
#include <openssl/rsa.h>RSA_private_encrypt(int flen, const unsigned char *from, unsigned char *to, RSA *rsa, int padding);
RSA_public_decrypt(int flen, const unsigned char *from, unsigned char *to, RSA *rsa, int padding);
DESCRIPTION
These functions handle RSA signatures at a low level.- RSA_PKCS1_PADDING
- PKCS #1 v1.5 padding. This function does not handle the algorithmIdentifier specified in PKCS #1. When generating or verifying PKCS #1 signatures, RSA_sign(3) and RSA_verify(3) should be used.
- RSA_NO_PADDING
- Raw RSA signature. This mode should only be used to implement cryptographically sound padding modes in the application code. Signing user data directly with RSA is insecure.
