Cryptography

Encryption is the process of converting plaintext to encrypted text. Encrypted text hides the original data from unauthorized users since encrypted text cannot...

You probably have heard about VPNs before. It’s even possible that you might have used one. In this post, we will be learning about VPN, some of its basic...

RC4 stands for Rivest Cipher 4. RC4 is a stream cipher and was invented by Ron Rivest in 1987. Since RC4 is a stream cipher, it encrypts the stream of data...

Stream ciphers fall under the symmetric encryption category. Thus, using stream ciphers the sender and the recipient of the data use the same key to encrypt...

Many organizations make use of cryptography for securing their applications. A large portion of banking applications rely on some sort of cryptography. When...

Block ciphers fall under the symmetric encryption category. Thus, using block ciphers the sender and the recipient of the data use the same key to encrypt and...

In the previous articles about credential management, we discussed how credentials can be used in applications and what can go wrong when dealing with credentials...

In the previous article, we discussed some examples of poor credential management. Hardcoded credentials, improper error handling and insecure data storage...

As discussed in the previous article, use of credentials is one of the most common approaches used in applications and this is the de facto method that users...

Cryptography is used in software to protect the data from adversaries. The key principles of cryptography is to provide confidentiality, integrity and authenticity...
