Added Functions

function_name function_type description comment examples
crypto_hash scalar Computes a cryptographic hash of the input value using the specified algorithm. Supported algorithms: blake3, sha2-256, sha2-512, sha3-256, sha3-512, md5, sha1, and more. Accepts strings, integers, floats, dates, timestamps, UUIDs, and lists of fixed-length types. NULL [crypto_hash('sha2-256', 'hello world'), crypto_hash('blake3', 42), crypto_hash('sha2-256', [1, 2, 3])]
crypto_hash_agg aggregate Computes a cryptographic hash over multiple rows using the specified algorithm. ORDER BY is required to ensure deterministic results. Returns the same hash as crypto_hash() would for an equivalent ordered list. Returns NULL for empty result sets. NULL [crypto_hash_agg('sha2-256', column_name ORDER BY id), crypto_hash_agg('blake3', data ORDER BY timestamp)]
crypto_hmac scalar Computes an HMAC (Hash-based Message Authentication Code) of the message using the specified algorithm and key. Supports all hash algorithms except blake3, which requires exactly 32 bytes for the key. NULL [crypto_hmac('sha2-256', 'secret_key', 'message to authenticate')]
crypto_random_bytes scalar Generates cryptographically secure random bytes using OpenSSL's RAND_bytes(). Length must be between 1 and 4,294,967,295 bytes. Each call produces different random bytes. NULL [crypto_random_bytes(16), crypto_random_bytes(32)]
