What is RIPEMD-320?

RIPEMD-320 is a cryptographic hash function from the RIPEMD family that produces a 320-bit fixed-size digest, developed in 1996 by Dobbertin, Bosselaers, and Preneel. It provides the same security level as RIPEMD-160 and has not been compromised by collision attacks, making it suitable for applications requiring longer hash outputs while maintaining adequate cryptographic strength. This browser-based tool generates RIPEMD-320 hashes instantly and privately—nothing is uploaded to servers, no sign-up required, completely free.

How RIPEMD-320 works

RIPEMD-320 uses the Merkle-Damgård construction with a one-way compression function to hash data into a 320-bit fingerprint. Here's how it works:

  1. Message Preparation: The input text is padded and divided into 512-bit blocks.
  2. Compression Function: Each block is processed through iterative rounds using bitwise operations (AND, OR, XOR, NOT) and modular addition to transform the data.
  3. Parallel Processing: RIPEMD-320 runs five parallel 64-round sequences, unlike some other hash functions that use sequential rounds.
  4. Final Digest: The intermediate hash values are combined to produce the final 320-bit (40-character hexadecimal) hash output.

Key Property: Even a single character change in the input produces a completely different hash, making it useful for verifying data integrity.

Example Structure: An input like "Hello World" goes through the compression function in multiple 512-bit blocks, with each round applying logical operations and additions to derive the final 40-character hexadecimal digest. The exact output depends on the precise sequence of these operations across all rounds.

How to use

  1. Type or paste your text into the input box.
  2. The RIPEMD-320 hash is calculated automatically as you type.
  3. Choose your output encoding (Hex or Base64) if needed.
  4. Click Copy to copy the digest to your clipboard.

Common uses

  • Digital signatures and authentication - ensuring messages are unchanged and signed by the claimed sender
  • File integrity verification - confirming downloaded files or backups have not been corrupted or tampered with
  • Data deduplication - identifying duplicate data blocks by comparing hash values rather than full content
  • Blockchain and cryptocurrency applications - supporting hash-based proof-of-work and data integrity in distributed systems
  • Legacy system support - maintaining compatibility with older applications or protocols that specifically require RIPEMD-320 hashing

Frequently asked questions

What is the output size of RIPEMD-320?
RIPEMD-320 produces a 320-bit hash, displayed as 40 hexadecimal characters (each hex character represents 4 bits).
Is RIPEMD-320 secure?
Yes, RIPEMD-320 provides adequate security for most applications and has not been broken by collision attacks. However, SHA-256 and SHA-3 are more widely recommended for new projects due to greater adoption and analysis.
Can RIPEMD-320 be reversed to get the original input?
No, RIPEMD-320 is a one-way cryptographic function. It is computationally infeasible to reverse a hash back to its original input, which is why it is suitable for password hashing and data verification.
Is this tool secure to use?
Yes, this tool runs entirely in your browser with no server uploads or data logging. Your input never leaves your computer, ensuring complete privacy.
How fast is RIPEMD-320 compared to other hashes?
RIPEMD-320 is relatively fast, though SHA-256 and MD5 are generally faster. It is slower than RIPEMD-160 due to the larger 320-bit output size.
Why use RIPEMD-320 instead of SHA-256?
Use RIPEMD-320 when required by legacy systems, specific protocols, or applications designed around the RIPEMD family. For new applications, SHA-256 is the industry standard.
