Cryptography is the science of protecting sensitive information by transforming it into a code that is illegible to unauthorized users. Cryptographers use mathematics and computer algorithms to create cryptographic protocols and encryption techniques that allow data to be kept secure, in the same way a safe can be used to protect valuables from theft or destruction. Cryptographers are technology professionals specifically trained in the art and science of encrypting digital information, making them extremely valuable assets for businesses, governments, researchers and individuals looking to protect their sensitive data.
The demand for expert Cryptographers has grown significantly in recent years, as new laws have been introduced regulating data security and protection, forcing businesses of all types to recognize the importance of safeguarding sensitive information. As such, Cryptography has become an essential tool in a variety of industries, from healthcare to finance, marketing, law and many others.
Here’s some projects that our expert Cryptographers have made real:
- Creating presentations around cryptography
- Translating coding languages relevant to cryptography
- Constructing comparison studies between different cryptographic algorithms
- Developing secure network communication protocols through Diffie-Hellman key exchange and AES encryption
- Enveloping, signing and creating digital messages with .pfx certificates
- Extracting font names from documents written in Cyrillic
- Deconstructing cryptosmt tool - Ascon cipher – changing from 5 to 4 size s-box
- Simulating cryptocurrency risk levels
- Decrypting digital files using PGP private keys

A MonoAlphabetic Substitution Cipher maps individual plaintext letters to individual ciphertext letters, on a 1-to-1 unique basis. That is, every instance of a given letter always maps to the same ciphertext letter. Here's the ciphertext for a message enciphered in the way described above (this is a shift substitution cipher): Kyzj vetipgkzfe dvkyfu nrj ljvu sp Ifdrej ze Tvrjri'j nrij. What is the plaintext for this message? Given the approach described above, for a Shift Substitution Cipher, how many possibilities are there for a shift value? Is this a feasible task? Given the approach described above, for a MonoAlphabetic Substitution cipher, how many possibilities are there for character mappings? Is this a feasible task? What would you expect to happen in this case?...

I am looking for a skilled .NET developer with experience in C# to debug and fix a signature generation program for a Web API. The current issue with the program is that it is throwing an error during execution. The error is on getting the private key at statment var CertRsa = as RSACryptoServiceProvider; The error says "Error-Invalid provider type specified.rn" Requirements: - Proficiency in .NET and C# - Strong debugging skills - Experience with signature generation programs The client has error messages and logs available, which can be provided for better understanding of the issue. The expected timeframe for the debugging and fixing is immediate, within 24 hours. If you have the necessary skills and can dedicate your time to this project, please submit your proposal...
