About Base32
Base32 encodes binary data using 32 printable ASCII characters (A–Z, 2–7) with optional = padding. Defined in RFC 4648, it is commonly used in OTP tokens, DNSSEC, and systems where case-insensitive encoding is needed.
FAQ
What is Base32?
Base32 represents binary data using only uppercase letters A–Z and digits 2–7, making it safe for case-insensitive systems.
Why use Base32 over Base64?
Base32 avoids characters that cause issues in certain contexts (like +, /, = in URLs or filenames). It's case-insensitive and uses a smaller alphabet.
Is padding required?
Padding (=) ensures the output length is a multiple of 8. Some implementations accept unpadded Base32.
