base64.b16encode()

Base32 and Base16

Encodes bytes as Base16, hexadecimal with capital letters. The same as bytes.hex().upper(), but as bytes.

Syntax

base64.b16encode(s)

For plain hex output bytes.hex() is usually handier: it returns a str, uses lowercase and supports a separator. b16encode is for places that expect RFC 4648 Base16, uppercase and as bytes. The size doubles, the most wasteful format in the module.

Examples

import base64
print(base64.b16encode(b'\xca\xfe'), b'\xca\xfe'.hex())  # → b'CAFE' cafe
