SHA1 and TOTP

[DSMan195276]

It produced codes but not the correct one. I put my secretkey in FFXIV for example, and kept failing, went back to the python/qb64 worked perfect

I switched the following:

Code: (Select All)

key$ = "Hello!" + CHR$(&HDE) + CHR$(&HAD) + CHR$(&HBE) + CHR$(&HEF)

to

Code: (Select All)

key$ = "1234MYSECRETKEY567890" + CHR$(&HDE) + CHR$(&HAD) + CHR$(&HBE) + CHR$(&HEF)

again, codes kept popping up like normal. but they were not correct

Sorry, it's not super clear from your example, is `1234MYSECRETKEY567890` the base32 version or the binary version of your key? The C code does not do the decoding, so you have to provide it the decoded binary key.

Ex. The actual key for my test was `JBSWY3DPEHPK3PXP`, which when decoded as base32 produces the "Hello!" plus DEADBEEF string that I put in `key$`. The chances are high that your key will not be ASCII like my example one when decoded, so your key will just be a series of `CHR$()`s.
