Understanding Cryptography

Strengths and Vulnerabilities

• Cryptography is science of “scrambling” data so it

cannot be viewed by unauthorized users, making it

secure while being transmitted or stored

• When the recipient receives encrypted text or another

user wants to access stored information, it must be

decrypted with the cipher and key to produce the

original plaintext
