Hashly is an online hash calculator provided by hashly.org and operated by Voidfly Labs. It is aimed at developers and technical users, supporting text hashing, file hashing, and random hash generation, with a clear statement that “no data leaves your browser.” The page explains that all hash calculations are performed inside the browser: text, file contents, and hash outputs are not sent to a server, and the tool can even be verified while running offline.
The feature set is fairly comprehensive: text input supports UTF-8, Hex, Base64, and Binary, while output supports lowercase Hex, uppercase HEX, Base64, and Binary. Files can be added by drag-and-drop or selected through the file browser. Random hashes can be generated in batches of 10 to 500, with options to copy all results or download them as a CSV. Supported algorithm families include MDx, SHA-1, SHA-2, SHA-3, BLAKE, Keccak, RIPEMD, xxHash, and more. This covers common use cases such as SHA-256, while also supporting Ethereum/EVM’s Keccak-256, Bitcoin/OpenPGP’s RIPEMD-160, and xxHash3 for high-throughput non-cryptographic checksums.
The page states that most algorithms use Daninet’s hash-wasm WebAssembly library, MD2 uses a custom inline implementation based on RFC 1319, and RIPEMD uses nf404’s crypto-api. The FAQ is well written: rather than merely listing features, it explains the properties of hash functions, how to choose algorithms, differences between output formats, and the limitations of broken algorithms such as MD5 and SHA-1. It also clearly warns that these fast hashes are not suitable for password storage, where bcrypt, scrypt, or Argon2 should be used instead.
The terms of service state that the tool is free for both personal and professional use, with no account required. No paid plans, payment methods, API, SDK, CLI, open-source repository, or self-hosting instructions were found. The terms also state that the tool is provided “as-is,” with no guarantee that outputs are completely correct or suitable for a particular purpose. Security-critical use cases should be independently verified.
Its strengths are that it is free, requires no login, has a clear privacy-focused design, supports a broad range of algorithms, and provides professionally written explanations. It is suitable for development and debugging, file verification, blockchain hash calculations, teaching, and everyday integrity checks. The downside is that it remains a web-based tool, with no team collaboration, automation interface, or auditable deployment information. If you need to compute hashes in bulk within CI/CD pipelines or backend services, a local library or command-line tool should still be the first choice.
The page does not provide information about access from mainland China, network nodes, or payments, so availability is unknown. If access is unstable, alternatives include CyberChef, collections of online hash tools, or local options such as OpenSSL, sha256sum, and b3sum.
