pack-priv Class OpenSslPbeSecretKeyGenerator

Class Inheritance

extends Object

java.lang.Object
com.oracle.bmc.http.client.pki.OpenSslPbeSecretKeyGenerator

Imports

java.nio.ByteBuffer, .CharBuffer, java.nio.charset.StandardCharsets, java.security.MessageDigest, .NoSuchAlgorithmException, java.util.Arrays

Derives the secret key used for OpenSSL style encryption.

By default the message digest algorithm used is MD5 :(
The iteration count is 1
A digest of the password and a random 8 byte salt is produced
The digest is repeatedly generated until sufficient bytes have been generated for the specified key size
