What Is the SHA-512 Hash of "The quick brown fox jumps over the lazy dog"?
The SHA-512 hash of "The quick brown fox jumps over the lazy dog" is 07e547d9586f6a73f73fbac0435ed76951218fb7d0c8d788a309d785436bbb642e93a252a954f23912547d1e8a3b5ed6e1bfd7097821233fa0538f3db854fee6. This is a 128-character hexadecimal string representing 512 bits. Even a single-character change to the input produces a completely different hash due to the avalanche effect.
About SHA-512
SHA-512 is the largest member of the SHA-2 family, producing a 512-bit (128-character hex) hash. It is actually faster than SHA-256 on 64-bit processors because it operates on 64-bit words. SHA-512 is used in high-security applications, SSH key fingerprints, and some cryptocurrency protocols. Like SHA-256, it has no known practical vulnerabilities.
How SHA-512 Computes This Hash
- Pad the message to a multiple of 1024 bits (append 1 bit, zeros, then 128-bit length)
- Initialize eight 64-bit state variables (h0-h7) from the fractional parts of the square roots of the first 8 primes
- Expand each 1024-bit block into 80 64-bit words using sigma functions
- Process through 80 rounds using Ch, Maj, and two sigma functions with round constants derived from cube roots of the first 80 primes
- After all blocks, concatenate h0-h7 to produce the 512-bit digest

Frequently Asked Questions
Is SHA-512 safe to use in 2026?
SHA-512 remains cryptographically secure with no known practical attacks. It is safe for data integrity, digital signatures, and checksums. For password hashing, use bcrypt or Argon2 instead.
Can I reverse a SHA-512 hash?
No. SHA-512 is a one-way function. Common inputs like "The quick brown fox jumps over the lazy dog" can be found via rainbow tables, which is why you should never use plain SHA-512 for passwords -- use bcrypt or Argon2 instead.
What is the avalanche effect?
The avalanche effect means that a tiny change in the input (even one bit) causes roughly 50% of the output bits to change. This makes it impossible to predict the hash of a similar input from a known hash.
