Base64 ASCII encoding
PEM (originally “Privacy Enhanced Mail”) is the most common format for X. 509 certificates, CSRs, and cryptographic keys. A PEM file is a text file containing one or more items in Base64 ASCII encoding, each with plain-text headers and footers (e.g. —–BEGIN CERTIFICATE—– and —–END CERTIFICATE—– ).

PEM files are used to store SSL certificates and their associated private keys. Multiple certificates are in the full SSL chain, and they work in this order: The end-user certificate, which is assigned to your domain name by a certificate authority (CA). This is the file you use in nginx and Apache to encrypt HTTPS.
