We use sha1sum to calculate SHA-1 hash value of our packages. Clarification about the usage: We distribute some software packages, and we want users to be able to check that what they downloaded is ...
It is generally known that we choose our key-lengths, so they are unbreakable in a specific time frame. For example we choose 112 bit keys (=2048-bit RSA) to protect data for the next few years and we ...
I'm a student currently pursuing my Engineering in Computers. I'm planning to put all my knowledge in and try to actually implement something related to security. To be more specific I'm more ...
AFAIK, our current disk encryption methods (dm-crypt) preserve the key (as well as decrypted data) in RAM while the computer is running with an implicit assumption that the memory is volatile and key ...
Let's say Bob wants to send a message to Alice. This communication requires to achieve confidentiality, integrity, proof of origin, non-repudiation. Therefore we can use this cipher-text: ciphertext ...
How would we go about factoring Moore's law into exceedingly long password cracking estimates? Let's say we've got a 12 character password containing mixed-case alpha characters and numbers, i.e. ...
