sha3512

SHA3512 is a hypothetical cryptographic hash function in the SHA family designed to produce a 512-bit digest. It is not an official standard, and there is no formal specification published by standardization bodies such as NIST. The name appears in speculative discussions and some vendor proposals, typically as a 512-bit variant aligned with the SHA-3 family.

Design and properties

In concept, SHA3512 would use a sponge construction akin to Keccak/SHA-3, with a 1600-bit internal state and a rate configured to yield a 512-bit output. Padding and padding removal would follow conventions used by SHA-3-like constructions. The intended security profile would mirror that of other 512-bit SHA-3 variants, offering strong resistance to preimage and collision attacks, subject to the final parameterization. There are no official security proofs for an unstandardized variant.

Standardization and use

Because SHA3512 lacks formal standardization, there are no official test vectors, reference implementations, interoperability guidelines, or widely accepted security assessments. In practice, stakeholders needing a 512-bit digest typically rely on standardized algorithms such as SHA3-512 or SHA2-512.

Notes

The term SHA3512 may appear in speculative literature or design proposals. For vetted standards and interoperability, readers should refer to established SHA-3 family specifications and widely adopted hash functions.
