While Encrypting a File with a Password from the Command Line using OpenSSL is very useful in its own right, the real power of the OpenSSL library is its ability to support the use of public key cryptograph for encrypting or validating data in an unattended manner (where the password is not required to encrypt) is done with public keys.. If they are stored in a file calledÃ‚Â Ã‚Â Ã‚Â Ã‚Â Ã‚Â Ã‚Â Ã‚Â Ã‚Â mycert.pem, you can construct a decrypted version called newcert.pem in two steps. One tiny difference: you might be asked to input the passphrase once. This is just what I needed. The typical process for creating an SSL certificate is as follows: # openssl genrsa -des3 -out www.key 2048 Note: When creating the key, you can avoid entering the initial passphrase altogether using: # openssl genrsa -out www.key 2048 At this point it is asking for a PASS PHRASE (which I will describe how to remove): […] Since it’s a command line tool, you need to understand what you’re doing.
