Simple golang lib for TLS Trust On First Use which can be used to establish trust for self-signed server certificates.

This fork has been modified to use sha256 hashing and excludes the 'SHA256 Fingerprint=' prefix when obtaining the fingerprint of the certificate

First, call GetFingerprints to retrieve the server certificate details. The user should then perform validation through some side-band channel. Once the user has verified the certificate fingerprint, the fingerprint can be stored, and used for subsequent connections to the server.

See example/main.go for an example using this library.
