Function bcrypt_pbkdf 

pub fn bcrypt_pbkdf(
    passphrase: impl AsRef<[u8]>,
    salt: &[u8],
    rounds: u32,
    output: &mut [u8],
) -> Result<(), Error>

The bcrypt_pbkdf function.

Arguments

• passphrase - The passphrase to process.
• salt - The salt value to use as a byte vector.
• rounds - The number of rounds to apply.
• output - The resulting derived key is returned in this byte vector.

Returns

• Ok(()) if everything is fine.
• Err(Error::InvalidParamLen) if passphrase.is_empty() || salt.is_empty().
• Err(Error::InvalidRounds) if rounds == 0.
• Err(Error::InvalidOutputLen) if output.is_empty() || output.len() > 1024.
