ExcelPass easily adds password protection to Word, PowerPoint, Excel, PDF and ZIP files. The program supports drag-and-drop and can quickly encode one or more files to use standard security, meaning it can be opened by compatible viewers and editors, including Microsoft Office, LibreOffice, Adobe Acrobat, and many more. Both read and write protection are available (excluding ZIP files, which do not support write restrictions).

The program can also disable security via the same interface (click the unlock button). Functional in 64-bit.

Although there are a variety of other ways to add a password to Office and ZIP files, there is no PDF encryption component (either read or write) in the free versions of PDF-XChange, Foxit, and Adobe Acrobat. As a result, this is a very nice addition for PDF users.

Works fine for zip and pdf files but nothing happens on xls(x) and doc(x) files :(

Am I missing something?

@spicydog: there is a known bug with creating a read-only password, which is being explored by the author. However, I just recently tested view without issue, and had no issues with DOCX or ZIP files. Files were generated with Office 2010 and 7zip. Please post in forums (or on the github page) if you keep having issues.

SteganoG v1.30 Updated

billon on 6 Apr 2017

SteganoG hides an encrypted file inside a image file (BMP or RAW) and acts as a carrier. Also known as steganography, the program offers a variety of encryption algorithms including Blowfish, TEA, and Twofish.

Note that the included Skipjack and RC4 algorithms have known weaknesses.

Does not seem to decrypt properly when using blowfish. I am unsure if it is the encrypt of decrypt side that is causing the issue. RC4 encryption works perfectly.

Does not encrypt/decrypt properly with all methods, but RC4 works fine. When CompressData is enabled, the decrypted file is smaller sized. When CompressData is disabled, the decrypted file seems to be the correct size but it is not the original file (checksum mismatch/content unreadable).

What's the point of this recent update from v1.21 to v1.30 after all these years?
I've tried it and I can only get it to work for the weak RC4: it still doesn't work for the others (TEA, Skipjack, Blowfish and Twofish).
WTF?
