How to get:
- SHA256 hash of an existing key?
Something like this:SHA256:3VvabBNtRF0XEpYRFnIrhHX6tKZq/vzU+heb3dCYp+0 [email protected] - MD5 (is it MD5?) of an existing key?
Something like this:b6:bf:18:b8:72:83:b7:fb:7d:08:98:72:1f:9f:05:27 - Randomart for an existing key?
Something like this:
Install openssh and openssl packages which contain the commands.
# get the SHA256 and ascii art
ssh-keygen -l -v -f /path/to/publickey
# get the MD5 for private key
openssl pkey -in /path/to/privatekey -pubout -outform DER | openssl md5 -c
# get the MD5 for public key
openssl pkey -in /path/to/publickey -pubin -pubout -outform DER | openssl md5 -c
