What is a plaintext private key?
We often say that your control of the funds in your wallet depends on the
ownership and control of the corresponding private key. In blockchain
transactions, the private key is used to generate the signature necessary
for the payment currency to prove the ownership of the funds. The private
key must be kept confidential at all times because once it is leaked to athird party, assets under the protection of the private key will also be at
the risk of being stolen.
The private key is not stored in the network but is generated by the user
and stored in a file or simple database called a wallet. The private key
stored in the user's wallet is completely independent and can be
generated and managed by the user's wallet software without the need for
blockchain or network connection.
The format of the private key is a 64-bit hexadecimal hash value string,
such as:
56f759ece75f0ab1b783893cbe390288978d4d4ff24dd233245b4285f

PS: Users can use the plaintext private key to import the SuperEx HD wallet to
modify the password of the corresponding wallet.
