Kriptiranje jedne .txt datotekice

[matman]

Dajte predložite neki alat koji je neovisan o platformi (win, unixoidi) + ako je moguće da nije nekaj instalacijsko nego samo izvršno (pa tu dolazimo do problema platformi valjda)

Ja sam naletel na ovo, i ako sam dobro skužil izvršava se prek browsera (nisam detaljno proučil i nisam još probal).

Ali ako je tak i da samo trebam par fajlova uz kriptiranom datoteku imat na stiku (netrebaju nikakve instalacije) to bi bilo idealno.

Nisam siguran jel radi onako kak ti hoćeš, al definitivno probaj Truecrypt

Main Features:

* Creates a virtual encrypted disk within a file and mounts it as a real disk.

* Encrypts an entire partition or storage device such as USB flash drive or hard drive.

* Encrypts a partition or drive where Windows is installed (pre-boot authentication).

* Encryption is automatic, real-time (on-the-fly) and transparent.

* Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:

1) Hidden volume (steganography – more information may be found here).

2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data).

* Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS.

Further information regarding features of the software may be found in the documentation.
