JSignPdf is an open-source Java application that adds digital signatures to PDF documents.

Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists, security researchers, red teamers, digital forensics professionals, and CTF participants.

PCSecrets is a PC application that holds secret text data - protected by a master password and strong encryption. Use it as a password manager or just somewhere to hold any text data securely in one place. It can hold a second, hidden set of secrets that is undetectable and plausibly deniable. The program is also a PC counterpart of the Secrets for Android app. It uses the same data structure and provides synchronization that allows easy transfer of secrets between the two. For those who find the personal computer environment more comfortable for data entry and editing (i.e. a real keyboard), PCSecrets provides an alternative way to manage your secrets. ...

CrococryptFile is a file encryption tool which creates encrypted archives of files and folders. The encryption features of CrococryptFile can be compared to a ZIP utility that uses ZIP's AES encryption. However, there are significant differences. CrococryptFile... - encrypts all file and folder information including filenames, time/date and filesize information, - disguises any information of the archive's content, because all data and meta-data is simply integrated into a...

Erinaceus is an esoteric two dimensional programming language which uses bitmaps as sourcecode. It is turing complete and able to modify itself. It has been created with the goal to create a language that can be hidden in pictures easily.
