In this blog, you will learn about what a cipher is, its types, and examples of the cipher. Also, a Cipher is an algorithm used to encrypt and decrypt data.
According to the National Institute of Standards and Technology (NIST),plaintext refers to"intelligible data that has meaning and can be understood without the application of decryption," although this is one of several definitions NIST recognizes -- including the IETF definition.

Encryption Definition Encryption is a form of data security in which information is converted to ciphertext. Only authorized people who have the key can decipher the code and access the original plaintext information. In even simpler terms, encryption is a way to render data unreadable to an ...
Learn what is cryptanalysis, types of attacks, how it works, its various techniques/tools, and its use as a method of decrypting encrypted text into plaintext.
Cryptography is the use of mathematical concepts and rules to secure information and communications. Derived from the Greek word kryptos, which means hidden, the definition of cryptography refers to converting intelligible text into unintelligible text, and vice versa. Cryptographic techniques allow only ...
A stream cipher is a cryptographic cipher to convert (encrypt) text to produce ciphertext and back. Stream ciphers can be either synchronous or self-synchronizing. In a synchronous stream cipher, the keystream is generated independently of the plaintext and ciphertext, while self-synchronizing stre...
A combination of substitution and transposition is also often employed. Advertisements Cipher also refers to the encrypted text, cryptography system or encryption key for the original text. Encrypted text is also known as ciphertext. Plaintext is the original, unencrypted text. Techopedia Explains ...
Definition, History, and Examples Encryption is a cryptographic process in which the original plaintext is converted into something called ciphertext. The idea behind encryption is that only certain parties can decipher the converted ciphertext back to its original form. ...
What Is Data Encryption? A Definition Data encryption is the process of using a private key to convert data into an unreadable format, so no one else can read it, except for the owner of that private key. Because it prevents unauthorized parties from viewing the data, encryption is one of...
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 numeric system as a placeholder and represents the absence of quantity. 10 ...
