In fact, you asked for the modulus (n), and that's what you obtained. To get the entire public key, including the public exponent (e), use this: openssl x509 -pubkey -noout -in /home/certificates/MTA/MTA_DEVICE.cert.pem | openssl rsa -noout -text -pubin Then, do whatever is necessary to convert this output in something useful for you. -- Erwann ABALEA <[email protected]> ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [email protected] Automated List Manager [email protected]
