In my project we have an API, and many clients may send transactions to this API. Transactions should be signed. Clients may be written in any language (C++, C#, python, go, whatever), with any CPU …
I need a fixed length 64 Byte ECDSA signature with the NIST P-256 Curve. The implementation hast to use JCE. The following code sample can generate a signature and verify it. Provider provSign = …
I’m looking for the proper Java algorithm for password encryption, and I found that Java SDK provides PBKDF2WithHmacSHA1, but not PBKDF2WithHmacSHA256. I heard that HMAC-SHA256 will take more time …
I would like to achieve the same what this openssl command performs, but programmatically in Java: openssl pkcs7 -in toBeExported.p7c -inform DER -out certificate.pem -print_certs which means that …
I need to implement 256 bit AES encryption, but all the examples I have found online use a “KeyGenerator” to generate a 256 bit key, but I would like to use my own passkey. How can I create my own key?…
