org.nuxeo.ecm.core.blob.AESBlobStore.EncryptingOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

Enclosing class:

AESBlobStore

public static class AESBlobStore.EncryptingOutputStream
extends FilterOutputStream

Output stream that encrypts while writing.

Stream format version 1 (values are in network order):

• 10 bytes: magic number "NUXEOCRYPT"
• 1 byte: file format version = 1
• 1 byte: use keystore = 1, use PBKDF2 = 2
• if use PBKDF2:
  • 4 bytes: salt length = n
  • n bytes: salt data
• 4 bytes: IV length = p
• p bytes: IV data
• x bytes: encrypted stream
