Truecrypt is free, open source, onthefly encryption software for your laptop. Thats a very big salt, which prevents rainbow tables since any precomputed table would have to begin with 512. As for the question of whether using ripemd160 or ripemd256 is a good idea ripemd160 received a reasonable share of exposure and analysis, and seems robust. The cryptographic hash functions available for use in truecrypt are ripemd160, sha512, and whirlpool. In this step you need to choose where you wish the truecrypt volume to be created. No data stored on an encrypted volume can be read decrypted without using the correct.
