RSA_public_encrypt() encrypts the flen bytes at from (usually a session key) using the public key rsa and stores the ciphertext in to. to must point to RSA_size(rsa) bytes of memory. padding denotes one of the following modes:
#include <openssl/rsa.h> int RSA_public_encrypt(int flen, unsigned char *from. RSA_public_encrypt() encrypts the flen bytes at from (usually a session key).
RSA_private_encrypt() signs the flen bytes at from. Please report problems with this website to webmaster at openssl.org. Copyright © 2015.
