Function extendhash::md5::padding_length_for_input_length

pub fn padding_length_for_input_length(input_length: usize) -> usize

Compute the MD5 padding length (in bytes) for the given input length.

The result is always between 9 and 72 (inclusive).

Arguments

• input_length - The length of the input length. This value is used because the amount of padding is always such that the total padded string is a multiple of 64 bytes.

Returns

This function returns the amount of padding required for the given input length.

Example

let data = "This string will be hashed.";
let padding_length =
    md5::padding_length_for_input_length(data.len());
assert_eq!(data.len() + padding_length, 64);
