Kriptiranje jedne .txt datotekice
 

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 :goood:

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.
