📖Tool Introduction
SHA1 Hash Generator is a secure hash algorithm tool that converts data of any length into a fixed-length 160-bit (40 hexadecimal characters) digest. SHA1 is more secure than MD5 and widely used in digital signatures, version control systems, and data integrity verification. While SHA1 is no longer recommended for high-security applications, it still plays an important role in many legacy systems.
