It should be noted that both the stream ciphers and the block ciphers are a type of symmetric-key cryptography technique. The main difference between the two is that in Stream cipher, the plain text is taken le
Decryption is the reverse process of encryption. Decryption converts the ciphertext back to plaintext. The receiver has to use a decryption algorithm and a key to decipher the ciphertext. Deciphering is another word for decryption. The decryption algorithm is the reverse process of the encryption...

One-Time Pad was first described by Frank Miller in 1882 and then reinvented by Gilbert Vernam and Joseph Mauborgne in 1917. It is based on modular addition or XOR operation, which combines the plaintext and the key in a way that produces a random ciphertext. For example, if the plaintex...
If the secret key used by both parties is compromised, both sides of the transaction are at risk and can be decrypted. What is asymmetric encryption and how does it work? Asymmetric encryption, also known aspublic key encryption, converts plaintext to ciphertext using two i...
between clients (e.g., a browser or a native app) and servers. With TLS encryption, plaintext data is transformed into an unreadable text (called ciphertext) that only those with the secret key can access or decrypt. This helps to keep the data secure and protected from unauthorized users...
Explore the key differences between hashing and encryption, understanding their purposes, methods, and applications in data security.
In RSA public-key encryption [1] Alice encrypts a plaintext M using Bob's public key (n,e) to ciphertext C by C=Me(mod n) where n is the product of two large primes and e≥3 is an odd integer that is coprime to the order of Z∗n, the group of invertible elements of Zn...
And the same property should hold for a nonce as well, but since it doesn't instantiate something we call it a nonce? I.e: in AES-CTR mode the IV is a nonce+counter. And both are put in plaintext format in the beginning of the ciphertext. ...
Difference Between Cipher and Zero Table of Contents ADVERTISEMENTKey Differences A cipher is a method used in cryptography for converting plain text into scrambled text, making it unreadable without the key. Whereas, zero is a digit and a concept in mathematics that plays a critical role in the...
