Incognito wallet is 48, 56 or 64 bytes of apparently random data. Allows user to hide wallet data in a pre-existing file or on a disk partition (preferably filled in advance with random data). Can be used to hide wallet securely in unencrypted cloud storage or on paper, without revealing the nature of the data. Data may be written at a user-specified offset into the file or partition, in which case user must remember the offset. Each export operation uses a new random init vector to create different data each time. This allows the user to hide wallets at different locations on the Net without detection. User must remember hash preset in addition to passphrase (though trial and error can be used if it's forgotten). Fully integrated with address generation and tx signing operations.
