My goal is to use JWE with hybrid encryption (ECDH+AES) for exchanging sensitive data with another party. However, the example code I can find for various Java libraries doesn’t match my understanding of how ECDH or asymmetric encryption w… Continue reading How does JOSE/JWE make use of ECDH when encrypting/decrypting messages?
Google, Apple, Microsoft and other tech giants, as well as the FIDO Alliance, password managers and identity management vendors are all moving to passkeys, thanks to FIDO2.

CRL lists the revoked certificates of a CA by sending back to the user the Serial Number of each certificate, nothing related to the public key. I don’t know how it works for OCSP.
Is there a technical way on the CA side (beyond the organi… Continue reading How can I ensure that a CSR doesn’t rely on a revoked private key
I require the OpenSSL command to verify the certificate chain. In the certificate, the signature hash is signed by the signer’s private key.

In the Windows Certificate Store, during a request creation, there are options given for the private key to be ECDH (Key Usage: keyAgreement) and for RSA for encryption only (Key Usage: keyEncipherment):
ECDH,Microsoft Software Key Storag… Continue reading Microsoft Software Key Storage Provider for ECDH (Key Usage: keyAgreement) and for RSA encryption (Key Usage: keyEncipherment)
In RSA signatures, Alice signs the message using her private key, and Bob verifies the message using Alice’s public key.
If an attacker has the signed encrypted message, then can they also verify the message using Alice’s public key? If ye… Continue reading Digital Signatures [closed]
I know RSA is asymmetric (public / private) key.
But, is possible to generate only a
private key with rsa and using it as symmetric?
For example with openssl?
