Creating SHA Encrypted Values

[FourthWorld]

I'm looking forward to seeing the messageDigest function get updated, hopefully it will have some clear documentation to help users figure out the correct syntax to generate say a SHA3 hash or other hash types.

The syntax noted in the pull request I linked to seems pretty straightforward for all types:

Code: Select all

messageDigest(<type>, <message>)

Very nice.
I'm just stepping into this encryption bussiness.

I want to change a program whcih stores now plain text to a database. But it's better to change some sensitive data into encrypted data.
My idea was : encrypt--->Base64 encode--->store into database (base64 so it becomes a string instead of binarydata, so no hassle with trailing zeros as i have read here and there)
then Read again for DB -->Base64 decode--->decrypt

Have to test some things

So looking at the MessageDigest function, it does indeed spit out a digest of the data, but I was wondering how I would go about converting that into the alphanumeric string that you would get from Mark Smith's library or PHP.

For example, if I put Hello World into an online SHA256 generator, I get the string "A591A6D40BF420404A011733CFB7B190D62C65BF0BCDA32B57B277D9AD9F146E" and I honestly cannot remember how to convert a digest to the necessary string. It used to be in the dictionary for MD5Digest but has been taken out now.

Max's wiki still has it. I often find the wiki faster than the current dictionary and in many cases, it has additional information added for the entries (in this case, 2 comments go much further into it ).

LC returns the raw binary form of values returned from hashes, but you can transform binary data into hex with the binaryDecode function:

Code: Select all

on mouseup
   put HexHash("Hello World", "sha-256")
end mouseup

function HexHash pStr, pHashMethod
   put messageDigest(pStr, pHashMethod) into tmp
   get binaryDecode("H*", tmp, tHex)
   return tHex
end HexHash
