Is it doable the encryption kind has modified by means of the years and I must one way or the other 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 consumer.
Pockets encryption makes use of AES-256-CBC to encrypt solely the non-public keys which are held in a pockets. The keys are encrypted with a grasp key which is totally random. This grasp secret is 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 non-public keys
which are held in a pockets. The keys are encrypted with a grasp key
which is totally random. This grasp secret is 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 reality an identical to the early variations or if that is even the related supply file (although it is title and site suggests so).
It appears probably the encryption methodology is suitable between present and older variations.
I’d hope that any competent software program developer, when altering the encryption methodology, would implement a pockets model quantity or different indicator that might enable new software program to detect older pockets.dat recordsdata and both improve them silently or present an applicable message to the person.
I could also be improper although.
