Import¶

import encoding

API Reference¶

Hex¶

Function	Description
`encoding.hex_encode(data: str) -> str`	Encode to lowercase hex
`encoding.hex_decode(hex: str) -> str`	Decode hex string
`encoding.hex_encode_upper(data: str) -> str`	Encode to uppercase hex

Base64¶

Function	Description
`encoding.base64_encode(data: str) -> str`	Encode to base64 (RFC 4648)
`encoding.base64_decode(data: str) -> str`	Decode base64 string
`encoding.base64_url_encode(data: str) -> str`	URL-safe base64 (no padding)
`encoding.base64_url_decode(data: str) -> str`	Decode URL-safe base64

Examples¶

Hex encoding¶

import encoding

let hex = encoding.hex_encode("Hello")
print(hex)  # 48656c6c6f

let decoded = encoding.hex_decode(hex)
print(decoded)  # Hello

let upper = encoding.hex_encode_upper("Hello")
print(upper)  # 48656C6C6F

Base64 encoding¶

import encoding

let b64 = encoding.base64_encode("Hello, World!")
print(b64)  # SGVsbG8sIFdvcmxkIQ==

let decoded = encoding.base64_decode(b64)
print(decoded)  # Hello, World!

URL-safe base64¶

import encoding

# URL-safe variant: uses - and _ instead of + and /, no padding
let url_b64 = encoding.base64_url_encode("data with special chars?!")
print(url_b64)

let decoded = encoding.base64_url_decode(url_b64)
print(decoded)
