Subject: lib: rsa: export rsa_verify_with_pkey()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=491bfe86062464b892386e8c8dfe0069975ecedc;p=u-boot.git

lib: rsa: export rsa_verify_with_pkey()

This function will be used to implement public_key_verify_signature()
in a later patch. rsa_verify() is not suitable here because calculation
of message digest is not necessary.
