Decodes standard Base64 by default; set url_safe: true for the URL-safe alphabet.

fn base64_decode(text: String, url_safe: Bool = false, max_bytes: Optional[Int] = none) -> Result[Bytes, EncodingError]:

base64_encode Function#

Encodes bytes as standard Base64 by default; set url_safe: true for URL-safe text.

fn base64_encode(data: Bytes, url_safe: Bool = false) -> String:

hex_decode Function#

Decodes hexadecimal text. max_bytes bounds decoded output when supplied.

fn hex_decode(text: String, max_bytes: Optional[Int] = none) -> Result[Bytes, EncodingError]:

hex_encode Function#

Encodes each byte as two lowercase hexadecimal digits.

fn hex_encode(data: Bytes) -> String:
