rsa crypt & decrypt in vfp

Hi,

I'm still using visua lfoxpro and i'm trying your examples. One of them particularly interest me (rsa crypting and decrypting string) and it is said you can crypt with the public key and decrypt with the private key but you only use the private key ? Is there a reason??

I want to use private key for crypting and use the public key for decrypting. Is that possible??

Is it possible to decrypt directly from a signature with a public key??

Thank you in advance for your answers

Regards
