PrivateKey prikf = kf.generatePrivate(kspec) KeyFactory kf = KeyFactory.getInstance("RSA") PKCS8EncodedKeySpec kspec = new PKCS8EncodedKeySpec(keybytes) u have to make byte keybytes size of keyfile, better to read with RandomAccessFile now it (the privatekey) is saved, rightįileInputStream filein = new FileInputStream("rsaprivate.key") PKCS8EncodedKeySpec kspec = new PKCS8EncodedKeySpe (rsaKeyPair.getPrivate().getEncoded()) this is the thing you need to do to recover it from file afterwards KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA", "BC") įileOutputStream fos = new FileOutputStream("rsaprivate.key") example is not functional, but u might get the point checking it out. If u want to use file to store keys, but not keystore, (which might not be so-good-thing-to-do) here is on example doing it with BounceCastle provider and rsa. I can not tell you more (samples of code), i'm working on same subject and have not finished this part jeffYou have to store your generated key in a file or in a keystore with an alias, so that you can retrieve it later.
#VCE PLAYER ERROR RETRIEVING KEY TO DECRYPT FILE HTTP HOW TO#
How to generate the key, encrypt the password, and I need to encrypt a password and store theĮncrypted string in a config file using JCE. I'm new to cryptology and seem to be missing a simpleĬoncept. But, how do I store the key and later retrieve it? I know how to generate the key, encrypt the password, and store the ciphertext in a file. I need to encrypt a password and store the encrypted string in a config file using JCE. I'm new to cryptology and seem to be missing a simple concept.
