Sha256Digest

macro Sha256Digest(value: ExpressionSyntax, context: FreestandingMacroContext) -> ()

Namespace: Raven.Macros
Assembly: Raven.Macros.dll
Source file: Sha256Digest.rvn

Computes the SHA-256 digest of a literal value during compilation.

Import Raven.Macros.* to invoke the conventional sha256Digest! alias. The canonical Raven.Macros.Sha256Digest! spelling remains available when the alias is shadowed or the namespace is not imported. The Digest suffix distinguishes the macro from .NET hashing types such as SHA256.

String and character values are hashed as UTF-8. Boolean and numeric values use their culture-invariant textual representation, and null hashes an empty byte sequence. The macro expands to a lowercase hexadecimal string literal, so no hashing occurs at runtime.

Example

import Raven.Macros.*

let digest = sha256Digest!("hello")
