You have proven that you are a qualified \"Agent with PHP and Encryption Experience\". You have gained valuable experience both in building and in using encryption tools.\r\n\r\nKey points to review and remember:\r\n\r\nSymmetric key algorithms\r\n\"password encryption\"\r\nfast, can handle large amounts of data\r\nthe key or password must be shared secretly somehow\r\nAsymmetric key algorithms\r\n\"public-private keys\"\r\nslow, can only handle small amounts of data\r\npublic key can be shared openly\r\nChecksum/Hash\r\nWorks because same function inputs = same output\r\nUsed to verify data integrity\r\nDigital Signature\r\nChecksum with a public/private key added\r\nUsed to verify data integrity + authenticity\r\nIf you would like to learn more about code and cryptography, \"The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography\" by Simon Singh is an excellent book on both the history and techniques.\r\n\r\nIf you have any particular questions about the assignment or the feedback, email us at universitysupport@codepath.org."}}
