Description

• This tool generates the SHA256 hash of a given text.

Facts

• SHA-256 is a very commonly used hash function and a member of the SHA2 or SHA-2 algorithm family, which stands for Secure Hash Algorithm 2.
• SHA-256 is a cryptographic hash function which takes an input text and generates a 256-bit hash value which is 64 characters in length.
• The SHA-256 hash value of an empty string or empty file is e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855.
• SHA-256 is used for digital rights management to protect digital media such as music, movies, and e-books from unauthorized use.
• SHA-256 is also used in digital signatures to ensure the authenticity of the signer.
• SHA-256 is not reversible, meaning that it cannot be used to recover the original data from the hash.
• SHA-256 is widely used in secure communication protocols such as TLS/SSL, SSH and IPSec.
• SHA-256 is not vulnerable to collision attacks, which makes it a secure and reliable choice for important data.
• SHA-256 supports variable length input and produces a fixed-length output.
