drunken-bishop

OpenSSH fingerprint visualization algorithm in Rust. Just for my learning purpose.

Usage

See examples/basic.rs.

Handy CLI is available at src/main.rs.

$ cargo run --quiet -- -h
OpenSSH fingerprint visualization algorithm in Rust.

Usage: drunken-bishop [OPTIONS] [STRING]...

Arguments:
  [STRING]...  Strings to visualize. All strings will be joined with a space. If none, read from stdin

Options:
  -s, --sha256   Use SHA-256 digest of given string
  -v, --verbose  Verbose output
  -h, --help     Print help
  -V, --version  Print version

e.g.

$ cargo run --quiet -- --sha256 --verbose "hello world"

2024-05-14T05:56:44.200501Z DEBUG drunken_bishop: SHA-256: true    
2024-05-14T05:56:44.200510Z DEBUG drunken_bishop: Verbose: true
