Encryption and hashing are both important techniques used in information security, but they serve different purposes and have different methods of implementation.

Encryption is a process of converting plain text data into an unreadable format known as ciphertext. This is achieved by using a secret key or algorithm to transform the original data. The ciphertext can then be decrypted back to the original plain text form using the same key or algorithm. Encryption is commonly used to protect sensitive information during transmission or storage. The primary goal of encryption is to ensure the confidentiality of the data.

On the other hand, hashing is a process of converting any input of arbitrary length into a fixed-length output, known as a hash value. This is achieved by using a hash function that maps the input to the hash value. Hashing is commonly used to verify the integrity of data. The hash value is a unique representation of the original data, and any changes to the data will result in a different hash value. The primary goal of hashing is to ensure data integrity.

In summary, encryption and hashing are two different techniques used in information security with different objectives. Encryption is used to protect the confidentiality of data by converting it into an unreadable format, while hashing is used to verify the integrity of data by creating a unique hash value. Understanding the differences between encryption and hashing is important for implementing effective security measures in various applications.
