write_pem

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)

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.

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")
