OpenSSL is the true Swiss Army knife of certificate management, and just like with the real McCoy, you spend more time extracting the nail file when what you really want is the inflatable hacksaw. Cool Tip: Check whether an SSL Certificate or a CSR match a Private Key using the OpenSSL … The solution was to strip the .pem from everything outside of the CERTIFICATE and PRIVATE KEY sections and to invert the order which they appeared. To read .pem file I have written a util class called PemFile.java which will be used to handle pem file I/O operations. I had a problem today where Java keytool could read a X509 certificate file, but openssl could not. Openssl unable to load private key bad base64 decode. If the file content is binary, the certificate could be either DER or pkcs12/pfx. You can read the contents of a PEM certificate (cert.crt) using the 'openssl' command on Linux or Windows as follows: openssl x509 -in cert.crt -text . A PEM encoded certificate is a block of encoded text that contains all of the certificate information and public key. Convert P7B to PEM openssl rsa -in somefile.pem -out id_rsa Note: you don’t have to call the output file id_rsa, you will want to make sure that you don’t overwrite an existing id_rsa file. openssl pkcs12 -in certificate.pfx -out certificate.cer -nodes. Openssl can turn this into a .pem file with both public and private keys: openssl pkcs12 -in file-to-convert.p12 -out converted-file.pem -nodes A few other formats that show up from time to time: .der - A way to encode ASN.1 syntax in binary, a .pem file is just a Base64 encoded .der file. openssl is the standard open-source, command-line tool for manipulating SSL/TLS certificates on Linux, MacOS, and other UNIX-like systems.
