Colm O hEigeartaigh commented on WSS-399:
-----------------------------------------
In WSS4J 1.6.8 you will be able to configure a digest algorithm to use with RSA
OAEP either programmatically via WSSecEncrypt or else via the
"encryptionDigestAlgorithm" configuration tag.

> As stated on http://www.w3.org/TR/xmlenc-core/#sec-RSA-OAEP (and
> http://java.net/projects/metro/lists/users/archive/2008-05/message/12) there
> should be the possibility to set the message digest that is listed as
> MANDATORY (and shall be set in the generated output).
> QUOTE:
> 5.4.2 RSA-OAEP
> Identifier:
> http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p (REQUIRED)
> The RSAES-OAEP-ENCRYPT algorithm, as specified in RFC 2437 [PKCS1], takes
> three parameters. The two user specified parameters are a MANDATORY message
> digest function and an OPTIONAL encoding octet string OAEPparams. The message
> digest function is indicated by the Algorithm attribute of a child
> ds:DigestMethod element and the mask generation function, the third
> parameter, is always MGF1 with SHA1 (mgf1SHA1Identifier). Both the message
> digest and mask generation functions are used in the EME-OAEP-ENCODE
> operation as part of RSAES-OAEP-ENCRYPT. The encoding octet string is the
> base64 decoding of the content of an optional OAEPparams child element . If
> no OAEPparams child is provided, a null string is used.
