Re-encrypt a Vault Key

About the Vault Key

This tool decrypts a vault key and re-encrypts it with a new set of passwords. The tool uses Shamir's secret sharing scheme to split the encryption key into multiple parts, each of which is encrypted with a password by using scrypt and AES-256. All the parts are stored together to form the encrypted vault key.

None of your information is ever sent to a server.

1. Preparation

   For the safety of your sensitive information, make sure your internet is disconnected.

   Each person who is going to provide a password should take the time now to come up with a good password or passphrase, which will will use later to encrypt and decrypt your recovery phrase. Keep in mind that there is no password recovery feature here, and if your cryptocurrency is stolen because of a weak encryption password, your bank will not help you.

   Tips for a good password/passphrase

   
   

   • Use a unique password, not one that you've used elsewhere.
   • The longer, the better—aim for 12 characters long at minimum. Entire phrases make for the strongest passwords.
   • Make it impossible for someone else to guess—For short passwords, avoid using dictionary words or simple alterations of words. For passphrases, avoid common phrases or simple alterations of common phrases.
   • Use variety—include numbers, capital letters, and symbols.
   • Make it memorable—it should be easy for you to remember, but difficult for anyone else.
