What is an IDEA file?
Encrypted file created by Tresor, a file and folder encryption program; contains an encrypted file that can only be opened in the Tresor application with the same password that was used to encrypt it.
The IDEA file is encrypted using IDEA (International Data Encryption Algorithm) block encryption. it uses 64 bit data blocks and a 128 bit key length. It produces a 160-bit hash value from the password you create and uses 128 bits of the hash value for the IDEA encryption key. When you provide your password again, the file will be decrypted.
NOTE: Tresor requires Mac OS between 9.0 - 10.6 with Motorola 68k and PPC processors in order to run. IDEA files cannot be accessed in Mac 10.7 or later.
