How do I read a PEM file?

Certificate Decoder 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.

How do I view a certificate in PEM format?

  1. If the certificate is in text format, then it is in PEM format.
  2. You can read the contents of a PEM certificate (cert.crt) using the ‘openssl’ command on Linux or Windows as follows:
  3. openssl x509 -in cert.crt -text.
  4. If the file content is binary, the certificate could be either DER or pkcs12/pfx.

How do I get certificates from PEM files?

Converting Using OpenSSL

  1. Convert a DER file (.crt .cer .der) to PEM openssl x509 -inform der -in certificate.cer -out certificate.pem.
  2. Convert a PEM file to DER openssl x509 -outform der -in certificate.pem -out certificate.der.
  3. Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM.

Is PEM a key or cert?

pem contains the private encryption key. cert.

How do I decode a key file?

To decrypt the private key from the terminal:

  1. Open terminal.
  2. Run the open ssl command to decrypt the file $ openssl rsa -in -out Enter pass phrase for encrypted_private.key: writing RSA key.

How do I view Openssl certificates?

Check SSL certificate with OpenSSL Command

  1. Check Private key info: openssl rsa -text -in privateKey.key -noout.
  2. Check CSR info: openssl req -text -in CSR.csr -noout.
  3. View SSL certificate info: openssl x509 -text -in certificate.crt -noout.

How do I read an openssl certificate?

Answer

  1. Check a certificate. Check a certificate and return information about it (signing authority, expiration date, etc.
  2. Check a key. Check the SSL key and verify the consistency: openssl rsa -in server.key -check.
  3. Check a CSR.
  4. Verify a certificate and key matches.

How do I extract a private key and certificate from a PEM file using openssl?

To extract the certificate, use these commands, where cer is the file name that you want to use:

  1. openssl pkcs12 -in store.p12 -out cer.pem. This extracts the certificate in a . pem format.
  2. openssl x509 -outform der -in cer.pem -out cer.der. This formats the certificate in a . der format.

Are .CER and .PEM the same?

cer just stands for certificate. It is normally DER encoded data, but Windows may also accept PEM encoded data. You need to take a look at the content (e.g. using the file utility on posix systems) to see what is within the file to be 100% sure.

How do PEM certificates work?

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.
