Abstract: There are several alternative strategies that can be used when utilising cryptography to encrypt card information. Encryption's main objective in this situation is to prevent sensitive card information from being intercepted and used fraudulently, including the card number, expiration date, and security code.

Using SSL (Secure Socket Layer) or TLS (Transport Layer Security), which establishes a safe, encrypted connection between a website or app and the server where the card information is stored, is one popular method of encrypting card information. This is frequently used for online transactions, such as when paying with a mobile app or buying something from an e-commerce website.

Using end-to-end encryption is an alternative strategy that guarantees that card information is encrypted from the time it is entered into a device, website, or app until it reaches its destination. This is frequently used with tokenization, which exchanges the sensitive card information for a singular token that can be safely kept and used for upcoming transactions without disclosing the actual card data.

Additionally, a number of cryptographic protocols and algorithms, including AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), and ECC (Elliptic Curve Cryptography), can be used to encrypt card information. These algorithms and protocols jumble the data using intricate mathematical computations so that it cannot be decoded without the right decryption key.
