openssl (version 1.4.4)

fingerprint: OpenSSH fingerprint

Description

Calculates the OpenSSH fingerprint of a public key. This value should match what you get to see when connecting with SSH to a server. Note that some other systems might use a different algorithm to derive a (different) fingerprint for the same keypair.

Usage

fingerprint(key, hashfun = md5)

Arguments

key

a public or private key

hashfun

which hash function to use to calculate the fingerprint

Examples

# NOT RUN {
mykey <- rsa_keygen()
pubkey <- as.list(mykey)$pubkey
fingerprint(mykey)
fingerprint(pubkey)

# Some systems use other hash functions
fingerprint(pubkey, sha1)
fingerprint(pubkey, sha256)

# Other key types
fingerprint(dsa_keygen())
# }
