Key pairs have a public key to share and a private key not to share. Public keys from ssh-keygen and PuTTY are .PUB files. Ssh-keygen saves keys like id_rsa.pub in ~/ .ssh by default. SSH .PUB files authenticate users logging into servers. Servers store them, users keep private keys. PuTTY also makes .PUB files. They contain public keys. Extract the public key from a .pem file to a .pub file. A .csr file is a Certificate Signing Request.
Files ending in .pub may be public keys from Pretty Good Privacy. VisualNEO makes .pub files with publication source code. Use Publisher to open .pub files. Right-click unopenable .pubs. Public keys also communicate over networks.
