I'm looking to encrypt a file with OpenSSL functions (blowfish, des, rc4-- haven't picked one yet). Anyhow, after decrypting a file, I need to know if the file was correctly decrypted. The only way it ...

IPsec incorporates several cryptographic operations to ensure message authenticity, data integrity, and sender nonrepudiation. In this section we will describe the mechanics of these cryptographic ...

In the password security arms race, the bad guys are winning. Once-sturdy cryptographic “hashing” algorithms — pillars of online data security — are proving vulnerable to brute force attacks that use ...

Yet another security researcher is poking holes in the security of Mega, this time by pointing out that the confirmation messages e-mailed to new users can in many cases be cracked to reveal their ...

Cryptography secures digital data using algorithms, essential in private secure communications. Cryptos use cryptographic methods like asymmetric encryption and hash functions for transactions.
