v3.00 beta 63 SHA1 error

[illyria]

Seems the SHA1 module is broken.

Hashes that are almost identical except the first 2 chars both result in the same password recovered.

e.g.
02342XXXXXXXXe5f0077XXXXXXf81811fb8193:Hello!
03342XXXXXXXXe5f0077XXXXXXf81811fb8193:Hello!
04342XXXXXXXXe5f0077XXXXXXf81811fb8193:Hello!
05342XXXXXXXXe5f0077XXXXXXf81811fb8193:Hello!
...
69342XXXXXXXXe5f0077XXXXXXf81811fb8193:Hello!


Noticed in beta-59 (v3.00-beta-142-g9d2c24f) confirmed in beta-63 (v3.00-beta-148-g063abab), but may have existed before that.
