If you would like to obtain an SSL certificate from a certificate authority (CA), you must generate a certificate signing request (CSR). A symmetric key can be in the form of a password which you enter when prompted. Encrypt large file using OpenSSL Now we are ready to decrypt large file using OpenSSL encryption tool: $ openssl smime -encrypt -binary -aes-256-cbc -in large_file.img -out large_file.img.dat -outform DER public-key.pem The above command have encrypted your large_file.img and store it as large_file.img.dat: Open up a terminal and navigate to where the file is.

This key is being transferred in PEM format, however this time it is not the standard one, but specific and designed by OpenSSL geeks. For instance, to generate an RSA key, the command to use will be openssl genpkey. This is probably the most secure option but also impractical for many situations. The requested length will be 32 (since 32 bytes = 256 bits). To dump all of the information in a PKCS#12 file to the screen in PEM format, use this command:. However I'm asked for a PEM pass phrase for the private key file. I would like to set up ssl for an existing nginx server. Generate 2048-bit AES-256 Encrypted RSA Private Key .pem.
