Hash caller-supplied UTF-8 text deterministically with SHA-256 or SHA-512 and re
Hash caller-supplied UTF-8 text deterministically with SHA-256 or SHA-512 and return both hexadecimal and Base64 digests. Input is bounded to 100 KiB, no network request or external provider is used, and Forest never treats a digest as proof of authenticity or password security. Base mainnet USDC
