113# / Hash Lab

One character. A completely different fingerprint.

What happens when you add a single # to 113? Compare the actual cryptographic digests behind the name.

A small experiment in secure hashing. Built for curiosity, not a security benchmark.

274 of 512 output bits differ between 113 and 113#.

The output changes drastically when a single input character changes. Values are lowercase hexadecimal digests of the exact UTF-8 bytes shown above, without a trailing newline. The bit difference above compares these two examples only.

Beyond the gimmick

Security is about more than a hash.

113 HASH works on secure infrastructure, identity systems and technical project delivery. Cryptographic hashes are just one small piece of the picture.
