   extended_description: |
-    This extension, `crypto`, adds cryptographic hash functions and
-    the ability to calculate a HMAC to DuckDB's SQL engine.
+    `crypto` provides two functions:
+
+    - `crypto_hash` applies cryptographically secure hash functions
+    and returns the result as a hex encoded value.
+
+    - `crypto_hmac` calculates the HMAC using a secret key and a
+    specific hash function.
+
+    The supported hash functions are:
+      - `blake2b-512`
+      - `keccak224`
+      - `keccak256`
+      - `keccak384`
+      - `keccak512`
+      - `md4`
+      - `md5`
+      - `sha1`
+      - `sha2-224`
+      - `sha2-256`
+      - `sha2-384`
+      - `sha2-512`
+      - `sha3-224`
+      - `sha3-256`
+      - `sha3-384`
+      - `sha3-512`
