Encoding, Hashing & Input

Methods for character codes, Base64/hex/binary encoding, cryptographic digests and reading input.

Character codes

.ord() → int

The character code of the first character.

log "A".ord()  // 65

To go the other way (code → character) use the number method .chr(), e.g. (65).chr() → "A". See Number conversion.

Base64, hex & binary

.btoa() → string / .atob() → string

Base64-encode / decode the string.

log "hi".btoa()    // "aGk="
log "aGk=".atob()  // "hi"

.encodeHex() / .decodeHex() → string

Hex-encode / decode. (Imports osl/crypto.)

.encodeBin() / .decodeBin() → string

Binary-string encode / decode. (Imports osl/crypto.)

Hashing

.hashMD5() / .hashSHA1() / .hashSHA256() / .hashSHA512() → string

Returns the hex digest of the string using the named algorithm.

log "hi".hashSHA256()
// "8f434346648f6b96df89dda901c5176b10a6d83961dd3c1ac88b59b2dc327aa4"

Input

.ask() → result

Prints the string as a prompt and reads a line from standard input, returning a result.

auto answer = "Continue? ".ask().unwrapOr("no")
