📖Tool Introduction
SHA256 Hash Generator is the most important secure hash algorithm in the SHA-2 family, producing a fixed-length 256-bit (64 hexadecimal characters) digest. SHA256 is widely considered one of the most secure hash algorithms currently available, playing a core role in blockchain, digital certificates, password storage, and data integrity verification applications. Compared to SHA1 and MD5, SHA256 provides stronger security guarantees.
