RIPEMD-320 Hash Generator Online — Free RIPEMD-320 Checksum Tool
Use this free online RIPEMD-320 hash generator to compute a 320-bit cryptographic checksum for any text string, local file, or remote file URL — with optional HMAC key support for keyed hashing.
What is RIPEMD-320?
RIPEMD-320 is a cryptographic hash function designed by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel as part of the RIPEMD family, developed in Europe in the mid-1990s. It produces a fixed-length 320-bit (40-byte) digest from any input, represented as an 80-character hexadecimal string. RIPEMD-320 is an extension of RIPEMD-160, designed to provide a wider output while retaining a similar security profile. It is standardized and has no known practical collision vulnerabilities, making it a solid choice for integrity verification tasks where a longer digest than MD5 or SHA-1 is desired.
What is RIPEMD-320 used for?
RIPEMD-320 is primarily used in scenarios requiring a longer hash output for added collision resistance, without switching to the SHA-2 family. Common use cases include:
- File integrity verification — compare checksums before and after download or transfer to detect corruption or tampering.
- Digital fingerprinting — uniquely identify a file or data payload by its hash value.
- Software distribution — package maintainers publish RIPEMD-320 hashes alongside releases so users can verify authenticity.
- Data deduplication — detect duplicate files by comparing digests rather than byte-by-byte content.
- HMAC authentication — combine RIPEMD-320 with a secret key to produce a message authentication code (MAC) for API or data-pipeline integrity checks.
Note: like all general-purpose hash functions, RIPEMD-320 is not suitable for hashing passwords. Use a dedicated password-hashing algorithm (bcrypt, Argon2, scrypt) for that purpose.
HMAC and keyed hashing
This tool supports HMAC-RIPEMD-320, which applies a secret key to the hash computation. HMAC (Hash-based Message Authentication Code) turns a standard hash into a keyed authentication primitive, ensuring that only parties who know the key can verify or reproduce the digest. This is useful for signing data payloads, verifying webhook requests, or any scenario where the hash itself must be secret.
Frequently asked questions
What is the output length of a RIPEMD-320 hash?
RIPEMD-320 produces a 320-bit digest, represented as an 80-character hexadecimal string. This is longer than MD5 (32 chars), SHA-1 (40 chars), and RIPEMD-160 (40 chars), providing a larger output space and reduced collision probability.
Is RIPEMD-320 safe to use for file integrity checks?
Yes. RIPEMD-320 has no known practical collision attacks and is considered secure for file integrity and checksum purposes. It is not recommended for password storage — use a dedicated password-hashing function instead.
Is this RIPEMD-320 hash generator free to use?
Yes, it is completely free. No account, registration, or software installation is required — just paste your text or upload a file and get your hash instantly.
What happens to files I upload?
Files uploaded for hashing are processed on the server to compute the digest and are then deleted automatically. They are not stored, shared, or retained after the calculation is complete.
Can I hash a remote file using a URL?
Yes. You can provide a direct URL to a remote file and the tool will fetch and hash it server-side, returning the RIPEMD-320 checksum. This is useful for verifying download integrity without saving the file locally first.
