Function scrypt_simple

pub fn scrypt_simple(password: &str, params: &ScryptParams) -> Result<String>

scrypt_simple is a helper function that should be sufficient for the majority of cases where an application needs to use Scrypt to hash a password for storage. The result is a String that contains the parameters used as part of its encoding. The scrypt_check function may be used on a password to check if it is equal to a hashed value.

Format

The format of the output is a modified version of the Modular Crypt Format that encodes algorithm used and the parameter values. If all parameter values can each fit within a single byte, a compact format is used (format 0). However, if any value cannot, an expanded format where the r and p parameters are encoded using 4 bytes (format 1) is used. Both formats use a 128-bit salt and a 256-bit hash. The format is indicated as “rscrypt” which is short for “Rust Scrypt format.”

$rscrypt$$<base64(log_n,r,p)>$<base64(salt)>$<based64(hash)>$

Arguments

• password - The password to process as a str
• params - The ScryptParams to use
