A 128-bit encryption key can represent a total of (2^{128}) possible combinations. In terms of characters, if we consider using hexadecimal representation (where each character represents 4 bits), a 128-bit key would be represented by 32 hexadecimal characters. If using Base64 encoding, it would require 22 characters. The specific number of characters depends on the encoding method used.
Encryption is the process of making information unreadable except to intended recipient by means of codes, cyphers, steganography, etc.DES - Data Encryption Standard128 bit encryption - used by browsers to communicate with secure serversRSS - Proprietary large prime number based encryptionPGP - Open source encryption similar to RSSWEP - Wired Equivalence Privacy, 40 or 128 bit encryption for secure Wi-Fietc.
prime numbers only be used as encryption keys as in encryption the numbers are coded inj the form of 0s and 1s ,i.e binary form.
Smart cards typically use a combination of symmetric and asymmetric encryption. Common algorithms include AES (Advanced Encryption Standard) for symmetric encryption and RSA or ECC (Elliptic Curve Cryptography) for asymmetric encryption. These encryption methods help secure the data stored on the card and facilitate secure communication between the card and external systems. Additionally, smart cards often implement secure key management practices to protect sensitive cryptographic keys.
The primary cryptographic techniques for producing ciphertext involve symmetric and asymmetric encryption. Symmetric encryption uses a single key for both encryption and decryption, making it efficient for large amounts of data. Asymmetric encryption, on the other hand, uses a pair of keys (public and private) to enhance security, particularly for secure communications. Both methods rely on algorithms like AES for symmetric encryption and RSA or ECC for asymmetric encryption to transform plaintext into ciphertext.

Transposition cipher is a method of encryption that reshuffles the order of characters without changing them, often inserting characters between existing characters to hide the message. This technique does not change the characters themselves, only their positions within the message.

I think it is safe to believe that it depends on the processor architecture. When you say 128-bit computer, this may mean different things. There is no such thing as an "128 bit computer". The design may allow 128bit core (processor) in which case an int most likely be 128bit. Or it may imply that only the bus is 128 bit. Or both. One may assume that on the 128bit Intel processor when it becomes available , the size of an integer data type will be 128bit IF it has an 128bit core, and not just the bus.
The encryption algorithm that inserts characters between existing characters is known as the "Insertion cipher." This method works by adding extra characters, often randomly generated or derived from a key, into the plaintext to obscure its original form. While not widely used in modern cryptography due to its simplicity and vulnerability to analysis, it serves as an interesting example of a transformation technique in classical encryption methods.

People have developed many encryption algorithms. One particular encryption algorithm is the Rijndael algorithm, usually called the AES or Advanced Encryption Standard.
