Please find file attached: EVP_PKEY_asn1_set_item.patch.
This is a patch to allow setting item_verify and item_sign handlers
in the internal structure evp_pkey_asn1_method_st
These handlers are called when a signature is encountered requiring
special handling. For example, item_verify and item_sign are used
in the implementation of RSA-PSS (see crypto/rsa/rsa_ameth.c) to deal with
X509_ALGOR mirror-ASN.1 type.
Currently OpenSSL doesn't provide write access to item_verify and
item_sign fields from external engines and special handling for non-standard
signature algorithms is impossible.
Type of request: enhancement request.
Version of OpenSSL: 1.0.2a.
Operating system: doesn't matter.
Patch created using the command:
diff -rupN openssl-1.0.2a/ openssl-1.0.2a-EVP_PKEY_asn1_set_item/ >
To apply pach use following command in current OpenSSL root dev. directory:
patch -p1 -l -u -b -i EVP_PKEY_asn1_set_item.patch
