• xml (required): XML UDM value to canonicalize and hash

• algorithm (optional, default "SHA-256"): hash algorithm (e.g., "SHA-512")

echo '<Invoice id="1"><Total>100</Total></Invoice>' \
  | utlx -f xml -e 'c14nHash($input)'
# "a1b2c3d4e5..."  (SHA-256 hex digest of canonical form)

{
  digest256: c14nHash($input),
  digest512: c14nHash($input, "SHA-512")
}
