SecurityCrypto

public SecurityCrypto(String keyPath,
                      String cipherAlg,
                      Provider provider)
               throws Exception

Creates SecurityCrypto Object with the provided parameters. The object contains the key, cipher and algorithm used.

Parameters:

keyPath - this parameter contains the secret key.

cipherAlg - this is the cipher algorithm which will be used to create the cipher. If this parameter is null then the value of the property "com.ibm.di.securityTransformation" will be used. If the property has no value then a default value for the algorithm will be used - DES/ECB/NoPadding.

provider - this is the security provider which will be used to create the cipher. If the parameter is null then the "com.ibm.di.cryptoProviderName" property will be checked for the name of an already registered security provider and if not found then the cipher will be created without an explicit security provider.

Throws:

Exception - if an error occurs.
