public AlgorithmExtensions()

Method Details

isValid

public static boolean isValid(@NonNull
 @NonNull String serviceName,
 @NonNull
 @NonNull String algorithm)

Validates if the provided algorithm is supported for the given service name

Parameters:

serviceName - the name of the security service

algorithm - the algorithm to be validated

Returns:

true if the algorithm is supported, false otherwise

getAlgorithms

public static Set<String> getAlgorithms(@NonNull
 @NonNull String serviceName)

Retrieves a set of algorithms for the specified Java cryptographic service

This method calls the Security.getAlgorithms(String) method to obtain a set of algorithm names supported by the specified security service

Parameters:

serviceName - the name of the security service (e.g., "Cipher", "KeyAgreement", "MessageDigest", etc.) for which the supported algorithms are to be retrieved

Returns:

a Set of String containing the names of the algorithms supported by the specified security service. The set is not modifiable

Throws:

NullPointerException - if serviceName is null

See Also:

• Security.getAlgorithms(String)

getServiceNames

public static Set<String> getServiceNames(@NonNull
 @NonNull Provider provider)

Retrieves all specified Java cryptographic service names from the given Provider object

Parameters:

provider - the Provider object

Returns:

a set of all specified Java cryptographic service names from the given Provider object

getAllServiceNames

public static Set<String> getAllServiceNames(Provider[] providers)

Retrieves all specified Java cryptographic service names from the given Provider array object

Parameters:

providers - the array with the Provider objects

Returns:

a set of all specified Java cryptographic service names
