File formats
There are two commonly used file formats for certificates:
- DER (Distinguished Encoding Rules) is a binary encoding. A typical file extension would be .crt.
- PEM (Personal E-Mail) uses only printable characters and therefore allows for easy use with e-mail.
Trust list
To establish a TLS connection, the certificate of the server or of the issuing CA must be trusted. Therefore each client maintains a list of trusted certificates.
