SHA-512 Hash Calculator

SHA-512 digest

Client-side computation for analysis, verification, and learning. Do not paste production secrets into untrusted sites; prefer local tooling for key material.

Educational / engineering use. RSA mode uses tiny primes for illustration only—not for real key generation.

What is SHA-512 Hash Calculator?

A stronger variant of the SHA-2 family that outputs a 512-bit hash. Preferred in high-security applications where collision resistance and longer digest length are required over SHA-256.

SHA-512 Formula

SHA-512 uses 64-bit words over 80 rounds:

Σ0(a)=(a28)(a34)(a39)Σ0(a) = (a ⋙ 28) ⊕ (a ⋙ 34) ⊕ (a ⋙ 39)
Σ1(e)=(e14)(e18)(e41)Σ1(e) = (e ⋙ 14) ⊕ (e ⋙ 18) ⊕ (e ⋙ 41)
T1=h+Σ1(e)+Ch(e,f,g)+Ki+WiT1 = h + Σ1(e) + Ch(e,f,g) + K_i + W_i
T2=Σ0(a)+Maj(a,b,c)T2 = Σ0(a) + Maj(a,b,c)

Outputs a 512-bit digest.

SHA-512 Step-by-Step

  1. Provide input message.
  2. Convert to bytes.
  3. Run SHA-512 rounds.
  4. Produce 512-bit digest.
  5. Compare digest for integrity checks.

SHA-512 Worked Example

Input: "hello"

Step 1: Preprocess and split into 1024-bit blocks.

Step 2: Run 80 SHA-512 rounds on 64-bit words.

Result is a 512-bit digest:
