Function guidon::gencrypt[−][src]

pub fn gencrypt(data: &str, key: Option<&str>) -> Result<String>

Encrypt a string with the given key

The key can be provided by an environment variable GUIDON_KEY or by the key option. As of now, the environment variable will be used if set, even if a key is provided as an argument. A initialization vector (IV) can also be provided by environment variable GUIDON_IV. If not the default on will be used. The IV must be 16 chars.

Arguments

  • data: The message to encrypt
  • key: An option of the key to use. The key length should be 256.

Example

let key = "top_secret";
let enc_msg = gencrypt("Hello world !", Some(&key)).unwrap();
println!("{}", enc_msg);
