Export key or certificate

Source: R/write.R, R/writessh.R

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.

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)
