write_pem: Export key or certificate

In openssl: Toolkit for Encryption, Signatures and Certificates Based on OpenSSL

Export key or certificate

Description

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)

write_openssh_pem(key, 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
key	a private key

Details

The pkcs1 format is the old legacy format used by OpenSSH. PKCS1 does not support the new ed25519 keys, for which you need write_openssh_pem. For non-ssh clients, we recommend to simply use write_pem to export keys and certs into the recommended formats.

Examples

# Generate RSA keypair
key <- rsa_keygen()
pubkey <- key$pubkey

# Write to output formats
write_ssh(pubkey)
write_pem(pubkey)
write_pem(key, password = "super secret")
