Cryptography: Introduction to Cryptography Services

Cryptography: Introduction to Cryptography Services

• discover the key concepts covered in this course
• define the goals of information security
• describe cryptography services and associate those services with the goals of information security
• describe encryption and encryption history
• use CrypTool and the Caesar cipher
• describe symmetric encryption
• define common symmetric encryption algorithms
• demonstrate CryptTool and symmetric encryption
• describe asymmetric encryption
• define common asymmetric encryption algorithms
• describe the purpose of hashing
• define common hashing algorithms
• use CryptTool and hashing
• download and install CrypTool v1, create a text file, create an MD5 and SHA1 hash of the file, change the file and check the hash value again, and encrypt text with Caesar cipher

Discover two of the core cryptography services, encryption and hashing. Examine the goals of information security, symmetric and asymmetric encryption, and using the Caesar cipher.
