Tools & Capabilities Breakdown

Base64 Tools (2)

base64_encode

Encode UTF-8 text to Base64 / Base64URL / Base32 / Hex (keyless, offline). Set `variant` (default base64).

base64_decode

Decode Base64 / Base64URL / Base32 / Hex back to UTF-8 text (keyless, offline). Set `variant` (default base64).

Crc Tools (2)

crc32

Compute the CRC-32 (IEEE) checksum of UTF-8 text — the algorithm used by zip/gzip/PNG. Returns the unsigned 32-bit value and its hex form. Keyless, offline. (Error-detection checksum, not cryptographic.)

adler32

Compute the Adler-32 checksum of UTF-8 text (as used by zlib). Returns the unsigned value and hex. Keyless, offline.
