Isn't "hash" a computer programming term for managing data? I think that's probably where the "hashtag" term originated.
A hash function is a function that creates a fixed length (usually a much shorter) representation of a variable length data set. The result is often called a hash.

Hash functions are often used for cryptographic purposes, like storing encrypted/hashed passwords, but also to check the validity of a certain data set.

Yet, I don't think the symbol # is related to those hash functions, although the "hash" symbol itself is very often used in computing. Most commonly as a starting indicator of a "single line" comment in many programming and scripting languages.
