we are facing the problem in RSA/ECB/OAEPWITHSHA-256ANDMGF1PADDING encryption in node.js decryption in java. below i can share my code in node: var nodeForgeRsaEncryption = function (data,publicKeyPem){ var buf = forge.util.createBuffer(data, 'utf8'); publicKey = forge.pki.publicKey...
This is the third entry in a blog series on using Java cryptography securely. The first entry provided an overview covering. The second one covered. This entry will teach you how to securely configure basic encryption/decryption primitives. This blog series should serve as a one-stop resource f...
In a pair of keys, the public key is visible to all. The private key is the secret key and is primarily used for decryption or for encryption with digital signatures. To implement asymmetric encryption in Java you first need to generate a keypair (public, private) by getting an instance ...

I hope to get some help, how to deal with the 20-bit key in order to make my normal decryption, thank you very much. hello, i have got the same question, if i don not use "new SecretKeySpec(password.getBytes(), KEY_ALGORITHM);" for instead in java, how to solved this problem ...
