getAlgorithm

getAlgorithm

Retrieves the active hashing algorithm by validating the object's configured properties, falling back to global configuration settings, or defaulting to a hardcoded safe fallback.

Usage

getAlgorithm(): string

Parameters

• Takes no arguments.

Return Value

(string) : Returns a string representing the validated hashing algorithm name (e.g., sha256, md5).

📌 The method determines which algorithm to return using a 3-step fallback chain:

1. Instance Property ($this->algo): Checks if an algorithm is explicitly set on the object instance and verifies its availability.

2. Global Configuration (getConfig('algorithm')): If the instance property is invalid or not set, it attempts to load the default algorithm from the configuration and validates it.

3. Hardcoded Fallback ('sha256'): If both of the above checks fail or are invalid, it defaults to returning 'sha256'.

Examples

$sec->getAlgorithm() = 'sha256'

Config Options

Config Key	Default Value	Allowed Values	Description
algorithm	sha256	string (See: )	Default hashing algorithm.
