Hash and Checksum

Enter text in MiniWebtool’s Adler32 Checksum Calculator to get its Adler-32 checksum in hexadecimal, decimal, and binary, plus the A and B parts.

Generate or verify a password hash with MiniWebtool’s Argon2 Hash Generator. Choose Argon2i, Argon2d, or Argon2id and adjust memory, iterations, parallelism, salt, and hash length to inspect the resulting encoded hash.

MiniWebtool’s Bcrypt Hash Generator / Checker creates bcrypt hashes at a chosen cost factor or tests whether a password matches an existing hash. A structural breakdown helps explain the salt, cost, and hash string.

Paste text or drop several files into MiniWebtool’s BLAKE2b Hash Generator to get BLAKE2b hashes at 256, 384, or 512 bits. Files are hashed byte for byte in your browser and listed together.

MiniWebtool’s CRC32 Checksum Calculator computes a 32-bit cyclic redundancy check from text in the selected encoding. Hexadecimal, decimal, and binary outputs help compare values when checking for accidental data changes.

Pick ECMA-182, ISO, Go-ISO, or XZ in MiniWebtool’s CRC64 Checksum Calculator, then check text or drop several files at once to get each file’s CRC64 from its original bytes, ready to copy or save.

MiniWebtool’s FNV-1a Hash Generator produces noncryptographic hashes at supported sizes from 32 to 1024 bits. Process text or batches and choose hexadecimal, decimal, or binary output for checksums, fingerprints, or hash-table experiments.

MiniWebtool’s MD5 Hash Generator calculates MD5 digests of text, or of many files at once from their real bytes, in hex or Base64. Use it for change detection; MD5 is not suitable for security-sensitive uses.

MiniWebtool’s MurmurHash3 Generator calculates non-cryptographic 32-bit and 128-bit hashes for text, or for a batch of files at once. Set a seed and compare decimal, hex, and binary output for testing.

Generate RIPEMD-160 digests from text, or from several files at once, with MiniWebtool’s RIPEMD-160 Hash Generator. Files are hashed byte for byte in your browser; compare a result with an expected hash.

MiniWebtool’s RSA Encryption Step-by-Step Simulator demonstrates RSA using two supplied primes. Follow public- and private-key generation, modular arithmetic, encryption, and decryption in an educational example rather than a production security workflow.

MiniWebtool’s SHA1 Hash Generator calculates the 160-bit SHA-1 digest of text, or of many files at once from their original bytes. Copy the list or save a checksum file, and compare a digest with another.

Convert text into a SHA-224 digest with MiniWebtool’s SHA224 Hash Generator. Choose input and output formats and optionally compare the generated hash with an existing digest.

Enter text, or drop several files into MiniWebtool’s SHA256 Hash Generator to get each 64-character SHA-256 checksum from the file’s real bytes, computed in your browser. Paste an expected hash to verify a match.

Enter text or drop several files into MiniWebtool’s SHA3-256 Hash Generator to get SHA3-256 digests, with files hashed byte for byte in your browser, and compare a result with an expected hash.

Use MiniWebtool’s SHA3-384 Hash Generator to calculate SHA3-384 digests of text, or of several files at once from their original bytes. Choose uppercase or lowercase hexadecimal and copy the results.

MiniWebtool’s SHA3-512 Hash Generator produces SHA3-512 fingerprints of text, or of a batch of files hashed byte for byte in your browser. Choose the output format and supply an expected digest to check a match.

Generate a text fingerprint with MiniWebtool’s SHA384 Hash Generator. The SHA-384 digest is available in multiple output formats, with comparison and copy controls for checking an expected value.

Get the SHA-512 digest of text, or of several files at once, with MiniWebtool’s SHA512 Hash Generator. Files are hashed from their original bytes in your browser; compare a result with a value you supply.

MiniWebtool’s Whirlpool Hash Generator calculates 512-bit Whirlpool digests from text, or from several files at once using their original bytes. Compare a fingerprint with an expected Whirlpool hash.
