Different RSA functions

[Heinz Markgraf]

Hi!

I would like to ask why there two pairs of RSA
functions. Would one not be enough?
What's the difference?


 int RSA_public_encrypt(int flen, unsigned char *from,
    unsigned char *to, RSA *rsa, int padding);
 int RSA_private_decrypt(int flen, unsigned char *from,
    unsigned char *to, RSA *rsa, int padding);
 int RSA_private_encrypt(int flen, unsigned char *from,
    unsigned char *to, RSA *rsa,int padding);
 int RSA_public_decrypt(int flen, unsigned char *from,
    unsigned char *to, RSA *rsa,int padding);


Thanks,

Heinz
