File Finger Print - support SHA-256

[IdeasVacuum]

Result$ = FileFingerprint(Filename$, Plugin [, Bits [, Offset [, Length]]])

So many download sites are now using SHA-256 file finger prints, it would be good to catch up since the likes of MD5 and SHA-1 were 'broken' long ago.

PB supports up to 512 Bits?

Bits (optional) The bits number to use for the fingerprint. It is only supported for the following plugin:
#PB_Cipher_SHA2 : can be 224, 256 (default), 384 or 512.
#PB_Cipher_SHA3 : can be 224, 256 (default), 384 or 512.

Hi

#PB_Cipher_SHA3 : can be 224, 256 (default), 384 or 512.

That doesn't make SHA-3 become SHA-256 though?

I don't know what you mean.
There are three SHA generations: SHA-1, SHA-2, and SHA-3.
The generation SHA-2 splits into SHA-224, SHA-256, SHA-384 and SHA-512, depending on the used bits.

So, what you mean with SHA-256 is just:

Code: Select all

FileFingerprint(FileName, #PB_Cipher_SHA2, 256)
