.pem Certificates
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
PEM certificates, often with the '.pem' file extension, are digital certificates used to establish secure communications over networks. They contain encoded cryptographic information such as public keys, private keys, and X.509 certificates, typically formatted in Base64 encoding. Commonly utilized in HTTPS, SSL/TLS configurations, and other security protocols, PEM certificates facilitate secure data transfer and identity verification across systems.
