archive created not extractable by 7z

Hi,

Not sure if it is known issues but 7z says:
```
ERROR: CRC Failed in encrypted file. Wrong password? : uploads/jenkins-DEPLOY-spc-r2r-43.log
```

If interested I will provide full test code. 7z is capable of extracting AES (type 99) based on various sources but I am not sure it is 7z bug, or this implementation bug.

Thanks
