Authorized responder for an OCSP response not validating with CertPathValidator
I’m trying to validate a certificate path with stapled OCSP checking through CertPathValidator. There might be some RFC-protocol that prohibits what I expect to validate just fine, but I’ve been unable to find this. Some paint art to describe relations between certificates discussed: overview When verifying the certificate path I get an exception stating that the responder is not authorized

Bouncy Castle Java PGP encryption & decryption
I am trying to implement PGP encryption in Java using Bouncy Castle, also using some of the examples provided by them. But if I try and decrypt the message I just encrypted, it does not work. The keys and the decryption method seem to be ok, because I can encrypt using an external tool (link) and then successfully decrypt it
Encryption/Decryption with bouncycastle-java and RSAES-OAEP
I am not an expert with encryption, but i am trying to create an CMSEnvelopedDataGenerator with bouncycastle 1.67, where the session key is encrypted with RSAES-OAEP (1.2.840.113549.1.1.7) For now my …
Loading pkcs12 file with BouncyCastle fails on unknown PRF algorithm (hmacWithSHA256)
we have a certificate in a pkcs#12 format provided by a 3rd party (not managed by us). We must sign emails with this certificate before sending them to this specific customer from our platform. There were no issues with the old certificate, but as it is about to expire we need to replace it by a newer one, which has

How read a PKCS8 encrypted Private key which is also encoded in DER with bouncycastle?
I have tried answers of these questions: Bouncy Castle : PEMReader => PEMParser Read an encrypted private key with bouncycastle/spongycastle However as my encrypted key is encoded in DER when I call object is null. I can convert it to PEM with this openssl’s command (it decrypts the key too) but I need to read the key in its original
