Subject: [PATCH] Set RSA_FLAG_EXT_PKEY flag
|
|
|
|
From docs:
|
|
"""
|
|
This flag means the private key operations will be handled by
|
|
rsa_mod_exp and that they do not depend on the private key
|
|
components being present:
|
|
for example a key stored in external hardware. Without this flag
|
|
bn_mod_exp gets called when private key components are absent.
|
|
"""
|
|
|
|
Setting this flag allows BIND to identify RSA key (stored on a HSM)
|
|
as a private key. Otherwise, BIND fails to sign and to verify signs.
|
|
|
|
Fixes: https://github.com/OpenSC/libp11/issues/304
|
|

(cherry picked from commit b487da5a0f69576139949d7235b988e822137cab)
