Description
| Returns the host key fingerprint of the server, which is automatically set after connecting to an SSH/SFTP server. The hashAlg can be any hash algorithm supported by Chilkat, such as "SHA256", "SHA384", "SHA512", "SHA1", "MD5", "SHA3-224", "SHA3-256", "SHA3-384", "SHA3-512", etc.
If both includeKeyType and includeHashName are 1, then the fingerprint string is formatted like this:
ssh-rsa SHA256:L7sQgnpnoBwRoyIYXAFBs8SdSnwtyYmhXs1p/mQDK...
If includeKeyType is 1 and includeHashName is 0:
ssh-rsa L7sQgnpnoBwRoyIYXAFBs8SdSnwtyYmhXs1p/mQDK...
If includeKeyType is 0 and includeHashName is 1:
SHA256:L7sQgnpnoBwRoyIYXAFBs8SdSnwtyYmhXs1p/mQDK...
f includeKeyType is 0 and includeHashName is 0:
L7sQgnpnoBwRoyIYXAFBs8SdSnwtyYmhXs1p/mQDK...
SSH host key types can be: ssh-rsa, ecdsa-*-* (such as ecdsa-sha2-nistp256), ssh-ed25519, and ssh-dss.
Returns Nothing on failure
