x509util

Go utility code for handling X.509 certificates.

Certificate Formats

This library handles certificates using the PKCS standards. Key formats supported include PKCS #1 for private keys and PKCS #8 for public keys.

Converting OpenSSH key formats to PKCS key formats

This section includes commands on converting OpenSSH key file formats to the PKCS formats used by this library.

Converting Private Keys from OpenSSH to PKCS #1

To decrypt OpenSSH Private Key to OpenSSL PKCS1 Private Key Format, run the following command, assuming the standard id_rsa private key file name

openssl rsa -in id_rsa -out id_rsa.private.pkcs1

Converting Public Keys from OpenSSH to PKCS #8

To convert OpenSSH Public Key to OpenSSL PKCS8 Public Key Format, assuming the standard id_rsa.pub public key file name.

ssh-keygen -e -m PKCS8 -f id_rsa.pub > id_rsa.public.pkcs8
