Our free SHA-1 hash generator quickly produces a 40-character hexadecimal (160-bit) hash, suitable for use as a secure secret password or key to protect sensitive data such as personal details or credit card information.
Developed by the U.S. National Security Agency, the SHA-1 algorithm is a federal standard for information processing. Once generated, the SHA-1 hash is irreversible.
What is an SHA-1 Hash?
SHA-1 (Secure Hash Algorithm 1) is a widely used hashing algorithm designed in 1995 to create a unique digital fingerprint for any data, including text, files, and passwords. However, due to vulnerabilities, it is now considered outdated, with SHA-2 being the recommended alternative.
SHA-2, introduced in 2001, includes variants like SHA-224, SHA-256, SHA-384, and SHA-512, which offer improved security for critical applications such as banking and email.
Overall, using more secure hashing algorithms is essential for protecting data and ensuring online security.
