Blowfish is a symmetric-key block cipher designed by Bruce Schneier in 1993. It is known for its simplicity and speed, making it one of the most popular algorithms for securing sensitive data. Here are the key features and details:
#SymmetricKeyEncryption: Blowfish uses the same key for both encryption and decryption, ensuring data confidentiality.
#BlockCipher: It processes data in fixed-size blocks of 64 bits, which makes it efficient for handling large amounts of data.
#KeySizeFlexibility: Blowfish allows a variable-length key from 32 bits to 448 bits, providing a flexible security level.
#FastAndEfficient: It is designed to be fast on 32-bit processors and does not require a large amount of memory, making it suitable for embedded systems.
#FeistelNetwork: The algorithm uses a Feistel network, which splits the data block into two halves and then processes them through multiple rounds of substitution and permutation.
#Security: Despite being one of the older encryption algorithms, Blowfish remains unbroken and secure against brute force attacks due to its key size.
#WideAdoption: It is widely used in various applications, including securing passwords, virtual private networks (VPNs), and file encryption.
Example
Password Encryption
Blowfish can be used to encrypt passwords in a database. When a user creates an account, their password is encrypted with Blowfish before storing it. This ensures that even if the database is breached, the actual passwords remain protected and unreadable without the decryption key.
