getKeyAlgorithm abstract method

String? getKeyAlgorithm(
  1. Mapping key, [
  2. String? defaultValue
])

Extracts the algorithm name from a key's metadata map.

Retrieves the algorithm identifier (e.g., "AES", "RSA") from a key's raw map representation, with a fallback default value if not found.

@param key - Raw key map containing algorithm metadata

@param defaultValue - Fallback value if algorithm is not found

@return Extracted algorithm name (or defaultValue if not present)

Implementation

String? getKeyAlgorithm(Mapping key, [String? defaultValue]);
