Listing All Available Encryption and Decryption Algorithms
Retrieving the list of available encryption/decryption algorithms
requires checking the services provided by all registered providers.
The retrieved list of names can be used in creating a Cipher object.
// This method is implemented in e194 Listing All Available Cryptographic Services
String[] names = getCryptoImpls("Cipher");
An example of the output:
Blowfish
DESede
PBEWithMD5AndTripleDES
TripleDES
DES
PBEWithMD5AndDES
