Try openssl pkey -in secure.key -out plain.key. Maybe add -text to get a decode in addition to the decrypted PEM. Or do openssl x509 -text on the cert to see what kind of key it contains; the private key should match that.. Extract all keys from .p12. # extract all keys. openssl pkcs12 -in certs.p12 -nocerts -out private_keys.pem # extract public key certificates. openssl pkcs12 -in certs.p12 -clcerts -nokeys -out.

openssl_private_encrypt() encrypts data with private private_key and stores the result into encrypted_data.Encrypted data can be decrypted via openssl_public_decrypt(). This function can be used e.g. to sign data (or its hash) to prove that it is not written by someone else. We would like to retrieve the private key from the PEM file. That's not DER format, that's RFC format. However at this point you must throw it away and start again, because you have just disclosed your so-called 'private' key to the world. From that point on it cannot possibly perform its sole function, which is to uniquely identify the owner.

openssl genrsa -out key.pem 2048 Where -out key.pem is the file containing the plain text private key, and 2048 is the numbits or keysize in bits. Completion of running this command will result in a 2048 key generated by openssl genrsa. openssl genrsa 4096 example without passphrase openssl genrsa -out key.pem 4096. From the Linux command line, you can easily check whether an SSL Certificate or a CSR match a Private Key using the OpenSSL utility. To make sure that the files are compatible, you can print and compare the values of the SSL Certificate modulus, the Private Key modulus and the CSR modulus. Cool Tip: Check the expiration date of the SSL.
