Collision probability between truncating vs subsequencing of SHA256 hash to 128 bits?
I am taking a SHA256 hash output in hexadecimal (64 hex nibbles), subsequencing it by taking every other character to make it 32 hex nibbles or 128 bits, and formatting it into a UUID string.
This isn’t being used for security purposes, ma… Continue reading Collision probability between truncating vs subsequencing of SHA256 hash to 128 bits?
