“PEM” (originally an acronym for “Privacy Enhanced Mail”) is a very common container format for digital certificates and keys that is used by Apache and other web server platforms. All of these “download” links will provide PEM files What Is a PEM File? This code assumes that a 2048-bit RSA key is used and draws a lot from this Ian Boyds answer. The only exception is the Microsoft IIS download, which is in PKCS#7/P7B format. ssh-keygen -i -m PKCS8 -f public-key.pem ssh-keygen -f private.pem -y > public.pub The following script would obtain the ci. public key certificate in base64-encoded DER format and convert it to an OpenSSH public key file. The following command will parse your PEM file and output the required RSA format used in authorizedkeys: ssh-keygen -y -f path/to/file. The OpenSSH format, supported in OpenSSH releases since 2014 and described in the PROTOCOL.key file in the source distribution, offers substantially better protection against offline password guessing and supports key comments in private keys. Say you have a private key in PEM format, and you want to use that key for SSH into another server, by adding an entry to your /.ssh/authorizedkeys file with the public key of such PEM file. The simple answer is that most files retrieved from the download table for a certificate in your SSL.com customer account will be in PEM format when you receive them. ssh-keygen write OpenSSH format private keys by default instead of using OpenSSL's PEM format. By default OpenSSH will write newly-generated private keys in its own format, but when converting public keys for export the default format is RFC4716. How Can I Download a PEM file from SSL.com? The supported key formats are: RFC4716 (RFC 4716/SSH2 public or private key), PKCS8 (PKCS8 public or private key) or PEM (PEM public key).
