Create a cryptography program using polyalphabetic or polygraphic with hash-function to encrypt and decrypt the digest should be fixed length no matter the input use python or java?
examples
would you like to encrypt or decrypt choose one
1. encrypt
2. decrypt
would you like to continue y/n
if a user schoose yes should loop back else terminate program
input: abc \rightarrow hash functions \rightarrow output: zbc3 d3lf
input: cats and dogs \rightarrow hash functions \rightarrow output: ac6q ppsh
input: laptops \rightarrow hash functions \rightarrow output: 8rtg kxwm
it should have a fixed length digest or output .

Solution: the categorization of functional and non-functional requirement are as follows: some of the more typical functional requirements include: • business rules• transaction corrections, adjustments and cancellations• administrative functions• authentication• authorization levels• audit tracking• external interfaces• certification requirements• reporting requirements• historical data• legal or regulatory requirementswhile,some typical non-functional requirements are: • performance – for example response time, throughput, utilization, static volumetric• scalability• capacity• availability• reliability• recoverability• maintainability• serviceability• security• regulatory• manageability• environmental• data integrity• usability• interoperability

The correct answer is, "definition" because you are typewriting information with a meaning. : ) hope this
