Base32, Base58 & Base64URL Converter
A developer utility to encode and decode data using various base encodings like Base32, Base58 (used in distributed ledgers), and URL-safe Base64URL.
Base encodings are methods for representing binary data in an ASCII string format. They are essential for transmitting data through channels that are designed to handle text. This tool covers several specialized base encodings used in modern computing.
Base32 encoding uses a 32-character set consisting of the uppercase letters A-Z and the digits 2-7. It's often used in scenarios where case-insensitivity is important, or where certain characters that look similar (like 0/O, 1/I) need to be avoided to prevent human transcription errors.
Base58 is a binary-to-text encoding scheme used in various distributed ledger technologies and other applications where human readability is a priority. It's similar to Base64 but avoids non-alphanumeric characters and letters that might look ambiguous when printed (0, O, I, l). This makes it easier for humans to read, type, and share.
Base64URL is a variant of the standard Base64 encoding. It makes the encoded data safe to use in URLs and filenames by replacing the '+' and '/' characters with '-' and '_', respectively. It also removes any trailing padding ('=') characters. It's commonly used in applications like JSON Web Tokens (JWTs).
