Functions

decode

fn (s: Str): Bytes

Decode s base64 string to a byte array.

Example

encoded "SGVsbG8="
bytes decode(encoded)
// bytes = [72, 101, 108, 108, 111]

decode-url

fn (s: Str): Bytes

Decode URL-safe base64 string (with or without padding) to bytes.

Example

decode-url("SGVsbG8")
// [72, 101, 108, 108, 111]

encode

fn (data: Bytes): Str

Encode data byte array to a base64 string.

Example

data [72, 101, 108, 108, 111]  // "Hello" as bytes
result encode(data)
// result = "SGVsbG8="

encode-url

fn (data: Str | Bytes): Str

Encode data to URL-safe base64 string (no padding). Uses - and _ instead of + and /. Safe for URLs and filenames.

Example

encode-url("Hello+World/Test")
// "SGVsbG8rV29ybGQvVGVzdA"  (no = padding, - and _ chars)

is-valid

fn (s: Str): Bool

Check if string s is valid base64.

Example

is-valid("SGVsbG8=")   // true
is-valid("not valid!") // false
