Is it attainable the encryption sort has modified by the years and I have to in some way improve my pockets.dat or one thing?
Based on https://en.bitcoin.it/wiki/Wallet_encryption
This web page describes the algorithm used for encrypting the pockets.dat file used within the authentic Bitcoin shopper.
Pockets encryption makes use of AES-256-CBC to encrypt solely the personal keys which might be held in a pockets. The keys are encrypted with a grasp key which is totally random. This grasp key’s then encrypted with AES-256-CBC with a key derived from the passphrase utilizing SHA-512 and OpenSSL’s EVP_BytesToKey and a dynamic variety of rounds decided by the pace of the machine which does the preliminary encryption (and is up to date primarily based on the pace of a pc which does a subsequent passphrase change)

Technical particulars of pockets encryption
Pockets encryption makes use of AES-256-CBC to encrypt solely the personal keys
which might be held in a pockets. The keys are encrypted with a grasp key
which is totally random. This grasp key’s then encrypted with
AES-256-CBC with a key derived from the passphrase utilizing SHA512 and
OpenSSL’s EVP_BytesToKey and a dynamic variety of rounds decided by
the pace of the machine which does the preliminary encryption (and is
up to date primarily based on the pace of a pc which does a subsequent
passphrase change).
The present model’s C++ code at https://github.com/bitcoin/bitcoin/blob/grasp/src/pockets/crypter.cpp mentions the identical algorithms however I have not tried to work out if the encryption is in truth equivalent to the early variations or if that is even the related supply file (although it is title and placement suggests so).
It appears possible the encryption technique is appropriate between present and older variations.
I’d hope that any competent software program developer, when altering the encryption technique, would implement a pockets model quantity or different indicator that may permit new software program to detect older pockets.dat recordsdata and both improve them silently or present an acceptable message to the person.
I could also be improper although.
