    ciphertext: impl AsRef<[u8]>,
    passphrase: impl AsRef<[u8]>
) -> Result<Vec<u8>>

Available on crate feature alloc only.

Decrypts ciphertext and into a newly allocated Vec.

This is a convenience function for using Decryptor::new and Decryptor::decrypt_to_vec.

Returns Err if any of the following are true:

• ciphertext is shorter than 156 bytes.
• The magic number is invalid.
• The version number is the unrecognized abcrypt version number.
• The Argon2 parameters are invalid.
• The Argon2 context is invalid.
• The MAC (authentication tag) of the header is invalid.
• The MAC (authentication tag) of the ciphertext is invalid.

Examples

let data = b"Hello, world!\n";
let ciphertext = include_bytes!("../tests/data/data.txt.abcrypt");
let passphrase = "passphrase";

let plaintext = abcrypt::decrypt(ciphertext, passphrase).unwrap();
