In my input source (a signed XML), I encounter some encrypted data. For example:

<cpix:Key>
    <enc:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p" />
    <enc:CipherData>
        <enc:CipherValue>rJXrk2Y...</enc:CipherValue>
    </enc:CipherData>
</cpix:Key>

The Algorithm attribute in tag EncryptionMethod denotes the algorithm being used.

Is there a canonical way to translate the algorithm URI to a Java/Cipher-compatible transformation format, which can be passed to Cipher.getInstance("...")?

In the example above, I believe this would be translated into Cipher.getInstance("RSA/ECB/OAEPPadding").
