![]() It’s a very old format.Ī simpler command without encryption would be : $ openssl genrsa -out out.key 2048Įncrypted, the key looks like this (“RSA PRIVATE KEY” with headers): -BEGIN RSA PRIVATE KEY- Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,7FC8C1B4B0FAC94A 6wj6oRh3NDj4aI5U2tI3YxhyZX++a9nhQ3c6uznDidO9pH91wYmMznfeLTNWLA5f Q/X5cDWFUY05XNVLDCuVosLumJ76fLi6yq/ZZ3rCgbglV415jdc3ozl9q1UANtp0 … -END RSA PRIVATE KEY. The output is by default the PEM format (it’s just the base64 of the DER format which is binary).If a program wants you to type a password - because you are using an encrypted private key - such as nginx or any openssl commands, you could need a human interaction. Note that for automation, you could get into troubles.It’s a secondary layer of security in case someone has access to the file. Any program trying to use the key will first need the password. It could also be passed from a file (“file:pwd.txt”). Here, it is provided directly into the command line. We encrypt it with the Triple DES cipher using a password.It will also use some random signals to always get a different result. The process has to generate 2 primes numbers and do some security checks (represented by the “.” and “+”).
