Suggestion to Change RSASSA-PKCS1-v1_5 Padding Mode for Improved Security

[tianjk99]

Please check if there is an issue with signing using RSASSA-PKCS1-v1_5 padding mode.

It's important to note that the PKCS#1 v1.5 padding scheme is considered insecure due to vulnerabilities, such as the RSA-PKCS1-v1_5-Attack in RSA signatures. To enhance the security of your code, I would recommend considering a switch to the RSASSA-PSS (Probabilistic Signature Scheme) padding scheme.
