About SHA-256
SHA-256 is a widely used cryptographic hash function from the SHA-2 family. It produces a 256-bit (64-character hexadecimal) hash value. SHA-256 is considered very secure and is used in many security applications and protocols, including TLS, SSL, and blockchain technologies like Bitcoin.
The algorithm is designed to be computationally infeasible to reverse, meaning it is extremely difficult to generate the original input data from its hash value. Additionally, it is resistant to collision attacks, where two different inputs produce the same hash.
Note:SHA-256 is considered secure for modern applications. It is widely used in cryptographic systems and is a good choice for general-purpose hashing needs.
