When dealing with "SSL" (or more appropriately TLS) certificates, you'll encounter .pem .crt .cer .key .der files. So, what's the difference?
There are four basic types of certificate manipulations. View, Transform, Combination , and Extraction
.der encoded certificates are binary, so to view them, you use a slightly modified command: openssl x509 -in mycert.der -inform der -text -noout [1]
