Hello. :-) I want to just "encrypt" somthing with public key only. ("NOT the SIGNATURE. Only ENCRYPTION) how can I do it with OpenSSL? It seems no function do that. I find EVP_PKEY_(en|de)crypt(), but it's only works with RSA. (is RSA the only algorithm which can encrypt some data with publickey?) thanks. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
