First-class Cryptography Coders, Devs for Hire in Ukraine

Cryptography is a method of storing and transmitting data in a certain form so that only those for whom it is intended can read and process it. It is most often used to scramble plaintext into ciphertext, then back again. The cryptography has such goals as confidentiality that means that the information can’t be understood by anyone for whom it was unintended, integrity – impossibility to change information in storage or transit between the sender and the intended receiver without detecting a change, non-repudiation – the impossibility of denying one’s intentions when creating or transmitting information, and authentication – the ability to confirm the identity and the origin/destination of the information by the sender and receiver. The procedures and protocols that meet these criteria are cryptosystems. Cryptography also allows senders and receivers to authenticate each other through the use of key pairs – the various types of algorithms for encryption. They include Secret Key Cryptography (SKC), Public Key Cryptography (PKC) and hash functions used to ensure that a file has remained unchanged.

Questions and Answers related to Cryptography Development

How fast is Cryptography developing at the moment?

“The field is developing faster than ever. Since cryptography values safety, security and consistency over ‘new and shiny’ this might not be for the best. However as you correctly observed, it has reached some level of maturity, so now instead of making great strides forward it is making more strides sideways: Developing new applications for existing stuff, getting the details right and finding and fixing weaknesses…”

What are the disadvantages of 128-bit encryption?

“There is not an encryption algorithm called “128–bit” but rather it is referring to the relative strength of the algorithm. There are a lot of factors that go into whether an algorithm is strong or not and this is just one part of it. If deployed correctly it will provide you with enough strength to withstand most attacks that a normal person could expect to experience. If it is not deployed properly then 1024 bit encryption will fail you eventually…”

What is the best way to encrypt sensitive data stored in a DB?

“It depends on how sensitive is the data. Having decryption keys (either symmetric key or private key) on the same host with DB is a bad call. In case that host is compromised, your entire DB is as good as plaintext. Even if you use application layer crypto, it won’t be hard to reverse engineer what exact algorithm(s) were used, and your DB is as good as plaintext again. What I would do is to generate a strong keypair…”

Cryptography: Is java helpful for cryptographic applications?

“If you have a crypto library (e.g. Bouncy Castle), then calling it from Java is fine. It’s easier to avoid buffer overflows than with C/C++, but it’s slightly trickier to make sure that sensitive data is truly erased. As for actually implementing cryptographic primitives, Java isn’t terrible but I’d recommend C or C++ instead. Achieving protection against side channels (eg timing attacks) and achieving good performance require very careful control over what the computer is doing, and many algorithms require more control over the system than Java provides.”
