In a discussion about Bitcoin security, Adam Back and Craig raise concerns about the current functionality of Bitcoin wallets. Craig suggests using the JSON API to unlock a wallet without displaying the password on the console screen, but Adam Back points out that this method may not work on all systems and could be vulnerable to spyware monitoring passwords. Adam Back also raises the issue of needing a way to transfer BTC off a specific address without spending the entire wallet balance, which creates more network traffic, higher fees, and damages privacy.At ZKS, pseudonyms are used to segregate online linkability for different purposes, but people still make mistakes and accidentally link all their coin sources. There is a need for a privacy algorithm to minimize cross-linking of coin sources and allow users to control which address the payment is from. Misbehavers could be blocked based on pseudonym in ZKS. The current Bitcoind's RPC client is not suitable for many features, and it would be better to provide a feature-rich Python RPC client. Instead of per-key fiddling in the GUI, it is recommended to use entire-wallet export and import. Coin control should be implemented for transferring BTC off a specific address.In an email thread from May 7, 2013, Adam Back, Pieter, and Gavin Andresen discuss possible improvements to Bitcoin's functionality. Adam Back suggests the need for a way to unlock the wallet without displaying the password on the console screen when importing a private key. Pieter recommends a Python RPC client with enhanced features, such as remembering passwords and batch lookups of compound commands. Adding a button to import a private key with an option to transfer it to another key is also discussed, but Pieter advises against per-key fiddling in the GUI. Instead, entire-wallet export and import are recommended. The need to transfer BTC off a specific address without spending the entire wallet balance is also raised, and Pieter suggests adding this capability to coin control.Gavin Andresen agrees with the idea of implementing a "sweep private key" feature and even suggests the possibility of periodic sweeping, although it would require remembering the key. However, he cautions against adding a user-friendly option to import private keys into the wallet due to potential dangers and confusion. Wladimir suggests censoring certain command arguments in the console screen and command line history to address the issue of displaying passwords. Overall, the discussions highlight the need for improvements in Bitcoin wallets, including enhanced security measures, better user experience, and privacy-preserving features. The developers propose various solutions, such as Python RPC clients, entire-wallet export/import, and coin control, to address these concerns.
