Base32 编码和解码

常见问题

Quick answers.

›What is the difference between Base32 and Base64?

Base32 uses a smaller character set consisting of uppercase letters and digits 2-7, making it case-insensitive and easier for humans to read or type manually. Base64 is more compact but includes lowercase letters and symbols like `+` and `/` which can be ambiguous in certain contexts.

›Why does Base32 use padding?

The equals sign `=` is used as a padding character to ensure the encoded output is a multiple of 8 characters. This helps decoders process the data in complete 40-bit blocks as specified by the RFC 4648 standard.

›Is my data secure when using this tool?

Yes. The encoding and decoding logic runs entirely within your browser's memory using JavaScript. Your input text or encoded strings are never transmitted to a server or stored in a database.

›What happens if I use lowercase letters in a Base32 string?

Standard Base32 is case-insensitive, so decoders typically treat lowercase letters like `a` the same as uppercase `A`. However, strictly following RFC 4648 usually produces uppercase characters by default.
