Export key or certificate

The write_pem functions exports a key or certificate to the standard base64 PEM format. For private keys it is possible to set a password.

Usage
write_pem(x, path = NULL, password = NULL)

write_der(x, path = NULL)

write_pkcs1(x, path = NULL, password = NULL)

write_ssh(pubkey, path = NULL)

Arguments
x

a public/private key or certificate object

path

file to write to. If NULL it returns the output as a string.

password

string or callback function to set password (only applicable for private keys).

pubkey

a public key

Details

The pkcs1 format is a legacy format which only supports RSA keys and should not be used anymore. It is only provided for compatibility with some old SSH clients. Simply use write_pem to export keys and certs to the recommended format.
