CAVEAT: i am not a lawyer, and this isn't legal advice. it is only meant to provoke further investigation.
Hi,
there's this section 43 of the Indian IT Act, 2000, which says in subsection b, that
[any person who, *without the owner's permission*] ==quote== (b) downloads, copies or extracts any data, computer data base or information from such computer, computer system or computer network including information or data held or stored in any removable storage medium; ==end quote== [could stand to be fined to the tune of up to a crore rupees].
this is sufficiently vague for the authorities to screw people who have not been permitted by sify to work with their cryptography.
of course, the law doesn't apply if your name is raju ;)
