1. As far as I can recall, the classic PKCS1 v1.x signing method wasn't
called PSS.
2. openssl 0.9.8l is old and lacks some security updates included in later
openssl 0.9.8 releases. Current 0.9.8 releases are 0.9.8o or (for new
projects) 1.0.0a .

Dear Mounir IDRASSI,
I am sorry for the wrong title in the last email.
I read your code. I am not sure about the lower-level encoding method.
For RSA_padding_add_PKCS1_PSS,
what's the encoding method it use, RSASSA-PKCS1-V1_5 or RSASSA-PSS? I
found a email chain in the archive,
http://www.mail-archive.com/openssl-users@openssl.org/msg40229.html,
which said that RSASSA-PSS is not supported in the openssl at that time.
I really appreciate your help. Before referring your code, I would
like to make sure the signature generation scheme. Thank you so much.
Regards,
Xiang
