Encrypt the Attribute with the given algorithm and key, where the data encryption key is encrypted with the given key encryption key.

The supported data encrytion algorithms are:

• Triple DES
• AES-128
• AES-192
• AES-256

The supported key encrytion algorithms are:

• RSA v1.5
• RSA-OAEP with MGF1
• TripleDES Key Wrap
• AES-128 Key Wrap
• AES-192 Key Wrap
• AES-256 Key Wrap

For RSA-OAEP, the following parameters are used:

• DigestMethod: SHA-1
• OAEPparams: null

Parameters:

attr - The attribute to encrypt.

dataEncAlg - The URI identifying the data encryption algorithm.
