z-base-32
z-base-32 is the Base32 variant designed by Zooko O'Whielacron, using an optimized alphabet that prioritizes human-readable characters to reduce transcription errors.
Purpose
It maximizes readability and error tolerance where binary data must be entered by hand or read aloud.
Mechanism
It uses the same 5-bit grouping as RFC 4648 Base32, but the alphabet is reordered to ybndrfg8ejkmcpqxot1uwisza345h769, placing easily confused characters at low-frequency positions.
Use cases
- One-time password backups
- Manual entry of keys
- Voice-readable encoding
