Paranoia File & Text Encryption for PC 🛡️

Files and Texts can be encrypted using a strong encryption algorithm: AES (Rijndael) 256bit, RC6 256bit, Serpent 256bit, Blowfish 448bit, and Twofish 256bit. The Pro Version additionally includes Threefish 1024bit, SHACAL-2 512bit, and Paranoia C4 2048bit. More details are available on the Pro Version page.
Steganography: Hide encrypted text or files inside JPEG images. Two algorithms are available: the classic F5 and the content-adaptive J-UNIWARD, which minimizes visual distortion and is harder to detect.
Secure Password Exchange (KEM): Securely exchange encryption passwords with another party using post-quantum ML-KEM (NIST FIPS 203). No password is ever transmitted directly — only encapsulated key material is exchanged.
Encrypt as URL: Encrypt files or text and generate a self-contained link that recipients can open in a web browser to recover the original data.
