Rules – New hash functions — sha1(), md5(), and sha512()

Cloudflare Rules supports three new hash functions: sha1(), md5(), and sha512(). Use them to compute hashes for systems that require these algorithms.

Like the existing sha256() function, each accepts a string or byte array and returns raw bytes:

For example, combine sha512() with encode_base64() to produce a Base64-encoded hash:

encode_base64(sha512("hello world"))

For details, refer to the sha1(), md5(), and sha512() function references.
