PEM File - What is a .pem file and how do I open it? (2024)
Secure certificates, like PEM-encoded X.509 certificates, are a way to verify the security and authenticity of an organization online. Organizations apply for certificates from third-party CA companies, such as Verisign or Thawte, and receive a secure certificate if they are deemed legitimate and trustworthy. The certificate is then uploaded to a secure web server to indicate that the organization's website is trustworthy, which is reassuring for Internet users making purchases and entering sensitive information online.
The Privacy Enhanced Mail (PEM) format was originally developed to secure mail in the 1990s but was never widely adopted. Instead, the PEM container was re-purposed for storing certificate-related information.
You most likely will not encounter a PEM file unless you are a webmaster since PEM certificate files are generated automatically and are not meant to be opened or edited manually. However, some secure websites may ask users to upload a PEM file (possibly sent in an email) in order to authenticate their identity.
If you do need to view the contents of a PEM file, you can open it with a text editor, such as Microsoft Notepad or Apple TextEdit. The file consists of one or more headers that indicate the information stored in the file. For example, a PEM file that contains an RSA private key and a certificate will look like this:
NOTE: PEM files are similar to .DER certificate files, but contain Base64-encoded text instead of binary data and are typically used by open source (Linux and Unix) web servers instead of Windows web servers. .CER and .CRT files are also saved in the PEM format but only store certificates.
A PEM file is a Privacy Enhanced Mail Certificate file. Open one with the program or operating system that requires the file (they all work a bit differently). Convert to PPK, PFX, or CRT with a command or special converter.

A PEM encoded certificate is a block of encoded text that contains all of the certificate information and public key. Another simple way to view the information in a certificate on a Windows machine is to just double-click the certificate file.
A PEM encoded file includes Base64 data. The private key is prefixed with a "-----BEGIN PRIVATE KEY-----" line and postfixed with an "-----END PRIVATE KEY-----". Certificates are prefixed with a "-----BEGIN CERTIFICATE-----" line and postfixed with an "-----END CERTIFICATE-----" line.
PEM is a container file format often used to store cryptographic keys. It's used for many different things, as it simply defines the structure and encoding type of the file used to store a bit of data.
key files are generally the private key, used by the server to encrypt and package data for verification by clients. . pem files are generally the public key, used by the client to verify and decrypt data sent by servers. PEM files could also be encoded private keys, so check the content if you're not sure.
A . pem file is a container format that may just include the public certificate or the entire certificate chain (private key, public key, root certificates): Private Key. Server Certificate (crt, puplic key)
If you cannot open your PEM file correctly, try to right-click or long-press the file.Then click "Open with" and choose an application. You can also display a PEM file directly in the browser: Just drag the file onto this browser window and drop it.
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----- ).
