FAQ
Is MD5 encryption?
MD5 is a hash (digest) algorithm, not encryption, and is irreversible. It is used for integrity checks; due to collision risks it is not recommended for password storage.
Difference between 32-bit and 16-bit MD5?
The 16-bit result is the middle 16 characters of the 32-bit digest (dropping 8 from each end), common in legacy systems; both come from the same computation.
Will my data be uploaded?
