unrar

[rogachez]

Hi, I have been using unrar for a while and I have the following problem:
when the .rar file is encrypted, it invariably extracts all but the last document in the file, and then prompts:

Encrypted file: CRC failed in [lastfile] (password incorrect ?)
Total errors: 1

The extraction of the last file stops at 99%, all the other contents are well handeled.

Any ideas?

Did it prompt you for a password?

[rogachez]

Yes, the full story is as follows:

prompt$ unrar e rarfile.rar

UNRAR 3.50 beta 3 freeware Copyright (c) 1993-2005 Alexander Roshal

Enter password (will not be echoed) for rarfile.rar:


Extracting from rarfile.rar

Extracting doc-001 OK
Extracting doc-002 OK
...
Extracting doc-042 99%
Encrypted file: CRC failed in doc-042 (password incorrect ?)
Total errors: 1

I swear I typed the password ok, every time. It does indeed extract all the files but the last one. At first, I didn't detect this because I tried with rars containing only one file. I thougth I had wrong paswords all the time. But the light came with many-filed rars, and the one-filed case does fit the picture, isn't it?

Is it possible that the file was corrupted? That's generally what CRC's are used to check for.

[rogachez]

Well, I should check if the same thing happens in Windows. But it would be too many coincidences. I have tried this with about a dozen of encrypted rars, and I have the same problem. By the way, the listing option ( unrar l rarfile.rar ) works perfectly fine.

try on this way

unrar e -p password something.rar

[rogachez]

Same effect:

Encrypted file: CRC failed in doc-042 (password incorrect ?)
Total errors: 1

It's not the prompt's fault.

[rogachez]

Well, the best solution seems to be the generalized use of the -kb option:

unrar e -kb something.rar

So sad.
