Thread: Cracking Hash with Known Plaintext
Post: RE: Cracking Hash with Known Plaintext
| depending on the algorithm, you could simply reverse the role of the password and the salt. for example, if the algorithm is md5(s.p), you could use the password as the salt and crack it as md5(p.s). |

Thread: Newb needing help cracking a DOCX file.
Post: RE: Newb needing help cracking a DOCX file.
| oclHashcat does not support MS Office documents.
Further, there is no hash in the document that you can crack. MS Office uses PBKDF2-HMAC-SHA1 to derive an encryption key to encrypt the document. |
