Function encrypt 

pub fn encrypt(
    plaintext: impl AsRef<[u8]>,
    password: impl AsRef<str>,
) -> Result<Vec<u8>>

Encrypts the plaintext with the given password and returns the ciphertext. The nonce is generated at each call to strengthen the encryption. Otherwise there’s a chance the key is weakened if the same nonce is used. The nonce is 24 byte (following the XCHACHA_NONCESIZE property). The ciphertext will be 40 bytes longer than the plaintext because of the XCHACHA_NONCESIZE + POLY1305_OUTSIZE size.

Format

{0,24: nonce} {24,: ciphertext} …

Arguments

• plaintext: The plaintext to encrypt
• password: The password to use for the encryption

Returns

The ciphertext
