What is SHA-512?
SHA-512 is a cryptographic hash function from the SHA-2 family that produces a 512-bit (128-character hexadecimal) digest. It uses 64-bit word operations internally, which makes it fast on modern 64-bit processors. SHA-512 is used in TLS certificates, digital signatures, and high-security integrity verification.

Frequently Asked Questions
When should I use SHA-512 instead of SHA-256?
SHA-512 is preferred when you need a longer hash for extra collision resistance, or when running on a 64-bit system where it may be faster. For most applications, SHA-256 is sufficient.
Is SHA-512 secure?
Yes. SHA-512 has no known vulnerabilities and is considered secure for all current cryptographic applications.
What is the difference between SHA-1 and SHA-512?
SHA-1 produces a 160-bit digest and has known collision vulnerabilities — it is no longer considered secure. SHA-512 produces a 512-bit digest and is part of the modern SHA-2 family with no known weaknesses.
Can I reverse a SHA-512 hash?
No. Like all SHA-2 variants, SHA-512 is a one-way function. The only way to reverse a hash is to try all possible inputs, which is computationally infeasible.
