SSH Host Key Fingerprint

See more SSH Examples

Demonstrates how to get the SSH server's host key fingerprint after connecting. Visual FoxPro

LOCAL lnSuccess
LOCAL loSsh
LOCAL lcHostname
LOCAL lnPort
LOCAL lcMd5_fingerprint
LOCAL lnIncludeKeyType
LOCAL lnIncludeHashName
LOCAL lcSha256_fingerprint

lnSuccess = 0

* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loSsh = CreateObject('Chilkat.Ssh')

lcHostname = "ssh.example.com"
lnPort = 22
lnSuccess = loSsh.Connect(lcHostname,lnPort)
IF (lnSuccess <> 1) THEN
    ? loSsh.LastErrorText
    RELEASE loSsh
    CANCEL
ENDIF

* Get the classic MD5 fingeprint
lcMd5_fingerprint = loSsh.HostKeyFingerprint
? lcMd5_fingerprint

* Sample output:
* ssh-rsa 3072 21:b0:d8:41:4e:ef:78:10:20:af:01:b7:71:5d:eb:94

* Starting in Chilkat v9.5.0.92, we can also get the SHA256 fingerprint.
* (it is also possible to get fingerprints using other hash algorithms such as SHA384, SHA512, etc.)

lnIncludeKeyType = 1
lnIncludeHashName = 1
lcSha256_fingerprint = loSsh.GetHostKeyFP("SHA256",lnIncludeKeyType,lnIncludeHashName)
? lcSha256_fingerprint

* Sample output:
* ssh-rsa SHA256:Ufgj480OsdsCZRjj9sSNM6fpgIcSJ61RsIG8usndUIY=

* The key type and hash name can be optionally included or not.
