Technical White Paper – Private and Public Key Cryptography and Ransomware
Cryptography is a method used to encrypt, or scramble, the contents of a file in such a way that only those with the knowledge of how to decrypt, or unscramble, the contents can read them. Ransomware, a type of malware that holds a computer or files for ransom, continues to highlight the malicious use of cryptography. CryptoLocker and CryptoWall are two of the most currently reported types of ransomware. Both encrypt the files on an infected system and demand payment for the ability to decrypt the files.
