The use of a hash allows programmers to avoid the embedding of password strings in their code.Hashes can be used as the basis of pseudo random character tables, and although not purely random, such methods can produce output quality that is at least as good as the in-built Rnd() function of VBA. That is to say, just a change in one character at the start will produce a completely different output. Hashes cannot be easily cracked to find the string that was used in their making and they are very sensitive to input change. A hash is an output string that resembles a pseudo random sequence, and is essentially unique for any string that is used as its starting value. ![]() The VBA code below generates the digests for the MD5, SHA1, SHA2-256, SHA2-384, and SHA2-512 hashes in this case for strings.
