Hi. What type of public key are you using? The OpenSSL implementation seems to have some issues with PKCS#1 RSA public keys. Please read the user comment about openssl_get_publickey about this issue (http://php.net/manual/en/function.openssl-pkey-get-public.php#101513). I strongly suggest to have a look at the error message from OpenSSL (openssl_error_string). /frank
