crypto/sha1

Imported as import "crypto/sha1" as sha1, its names are then sha1.…. Every signature below is the one the checker infers.

SHA-1 and base64, written in Rill. The WebSocket handshake needs both, and they are a fair test of the language's bit operations: everything here is 32-bit arithmetic emulated on 64-bit integers by masking after each step.

import "text/str" as str
str.hex_encode(sha1.sha1("abc"))   # => a9993e364706816aba3e25717850c26c9cd0d89d
sha1.base64(sha1.sha1("abc"))     # => qZk+NkcGgWq6PiVxeFDCbJzQ2J0=

Types

Digest

• Digest(a: Int, b: Int, c: Int, d: Int, e: Int)

Functions

fn sha1(msg: Str) -> Str

The digest as 20 raw bytes.

import "text/str" as str
str.hex_encode(sha1.sha1(""))      # => da39a3ee5e6b4b0d3255bfef95601890afd80709
#sha1.sha1("anything")           # => 20

fn base64(s: Str) -> Str

sha1.base64("hello")   # => aGVsbG8=
sha1.base64("")        # =>
