What is Tiger-128?
Tiger-128 is a truncated variant of the Tiger hash family, designed in 1995 by Ross Anderson and Eli Biham. The full Tiger algorithm produces a 192-bit digest; Tiger-128 keeps only the first 128 bits (16 bytes), making its output identical in length to MD5 while benefiting from Tiger’s more modern construction. Tiger was specifically optimised for 64-bit processors and offers very fast hashing on modern hardware. Like all members of the Tiger family, Tiger-128 is a Merkle–Damgård hash that processes data in 512-bit blocks.
The algorithm is not considered suitable for password storage — dedicated password-hashing functions such as bcrypt or Argon2 should be used for that purpose. For general-purpose file integrity verification and non-security-critical checksums, Tiger-128 remains a practical and fast choice.
Common uses for Tiger-128
- File integrity checks: compare a known Tiger-128 digest against a freshly computed one to detect accidental corruption or tampering during transfer.
- Deduplication: quickly identify duplicate files in a dataset by comparing their Tiger-128 hashes.
- Hash-table keying: Tiger’s speed on 64-bit hardware makes it attractive as a non-cryptographic hash for data structures.
- HMAC authentication: the tool supports HMAC mode, combining Tiger-128 with a secret key to produce a message authentication code for API or data-integrity workflows.
Tiger-128 vs. other 128-bit hashes
At 128 bits, Tiger-128 shares its digest length with MD5, MD4, and HAVAL-128. Compared with MD5, Tiger-128 has a stronger internal structure and was designed to resist the differential attacks that eventually broke MD5. However, for any application where collision resistance genuinely matters from a security perspective, a SHA-2 or SHA-3 variant with a longer output is the recommended choice. Use Tiger-128 where you need a fast, compact checksum and are not relying on the hash as a security boundary.
Frequently asked questions
What is the output length of a Tiger-128 hash?
Tiger-128 produces a 128-bit digest, which is typically represented as a 32-character hexadecimal string — the same length as an MD5 hash.
Is this Tiger-128 tool free to use?
Yes, it is completely free. No account, subscription, or software installation is required.
Can I hash a file as well as plain text?
Yes. You can type or paste any text directly, upload a local file, or provide a URL to a remote file and the tool will compute its Tiger-128 hash.
What is HMAC mode and when should I use it?
HMAC (Hash-based Message Authentication Code) combines the Tiger-128 algorithm with a secret key to produce an authentication code. Use it when you need to verify both the integrity and the authenticity of data, for example when signing API payloads or detecting unauthorised modifications.
Are uploaded files stored on your servers?
No. Files submitted for hashing are processed immediately and deleted automatically afterwards. They are not stored, shared, or retained.
