Random Hash Test-Data Generator
Create securely random, digest-shaped test fixtures in selected algorithm lengths without implying a known original message.
How to use
Choose a digest shape, count, and format. Most choices produce random bytes of the corresponding digest length rather than hashing a message; Adler-32 fixtures are valid checksums of random synthetic data.
Example
Limitations
Digest-shaped fixtures are not computed hashes and have no supplied original message. They must not be used as passwords or authentication tokens. SHA-0 and original BLAKE choices describe output shape only. Combined output, separators, and summary are limited to 1,000,000 characters; large counts and output lengths may exceed this limit together.
Frequently Asked Questions
Can I recover the source text for a generated value?
No source text exists for ordinary fixture mode: the tool generates random digest-length bytes directly.
Are repeated examples supposed to match?
No. Secure randomness makes each run and each item independent, so the documented example describes the format rather than a fixed value.
