Web4 de jan. de 2024 · I also noticed that N, E, D, P, and Q are actually being retrieved from PKSC1 private key, but QP, DP, DQ are computed based on D, P and Q. Seems like DP and DQ are being computed correctly, but QP is not. So if I overwrite QP with the value that is retrieved from PKSC1 private key - private decryption starts working as expected. WebOpenSSL allows you to generate shorter RSA keys. The shortest ones are 32 bits. But don't use them in production systems.
