To designate by characters.

An algorithm used in encryption.

Encrypted data that is unreadable until it has been converted into plain data (decrypted) with a key.

An algorithm that transforms data between plaintext and ciphertext.

A system of secret communication in which plaintext letters are substituted for or transposed in a specific and constant manner.

A system for concealing plain text by transposing the letters or numbers or substituting other letters or numbers according to a key. It is also called a "cryptosystem."

Any general system for hiding the meaning of a message by replacing each letter in the original message with another letter. The system should have some built-in flexibility, known as the key.

A cryptographic system in which units of plain text are substituted or transposed according to a predetermined key.

A set of rules to transform original information into coded form.

Procedure that transforms data between plaintext and ciphertext; a crypto algorithm.

A cryptographic algorithm for encryption and decryption.

means of encoding a readable message into an unreadable scrambled message. Data in unencrypted form is called plaintext; data in encoded form is called ciphertext.

A cryptographic algorithm that is used to encrypt data that is unreadable until it is converted into plain data (decrypted) with a predefined key.

The method of forming a hidden message. The cipher is used to transform a readable message called plaintext (also sometimes called cleartext) into an unreadable, scrambled, or hidden message called ciphertext. Only someone with a secret decoding key can convert the ciphertext back into its original plaintext. See also ciphertext; plaintext; cryptography.

encryption using substitution on the symbol level, not to be confused with a code

A system of encrypting a message by which units (usually letters) of ‘plain text' are arbitrarily transposed or substituted according to a pre-determined code (or cryptographic ‘key') to produce ‘ cipher text'. In theory, only those in possession of the key may be able to decrypt the message and reveal the original ‘plain text'.

In Cryptographic Support, data that is unintelligible to all except those who have the key to decode it to plaintext.

A mathematical function used for encryption and decryption

a cryptographic algorithm used to encrypt and decrypt files and messages.

A cryptographic algorithm used to encrypt data; that is, to transform plaintext into ciphertext using a predefined key.

1. A method of transforming texts character by character in order to conceal their meaning. 2. Such transformed messages.

Synonym for "cryptographic algorithm".

Any encryption algorithm. Ciphers can be classified according to whether they are symmetric or public key algorithms, and by whether they operate on their data as a stream or divided into blocks.

substitution of letters or numbers for the plain text message in order to hide the true letters

The type of encryption used (for a connection)

A mapping algorithm that is applied to a fixed number of characters at a time with an intent of concealing the contents of the message.

See cryptographic algorithm.

A method or system of changing text to hide its real meaning where each letter is changed to something else.

A cipher is a cryptographic algorithm (a mathematical function), used for encryption or decryption.

An algorithm or system for data encryption. Examples are DES, IDEA, RC4, etc. See: SSL/TLS Encryption

See cryptographic_algorithm.

A set of rules used to transform a message from plain text tocipher text, or to encrypted text. The cipher is a portion of an encryption scheme.

An algorithm for encryption or decryption. A cipher replaces a piece of information (an element of plain text) with another object, with the intent to conceal meaning. Typically, the replacement rule is governed by a secret key. See also: Encryption, Decryption.

An encryption - decryption algorithm.
