bip38tool

bip38tool

This tool generates bitcoin addresses and encrypts them using the BIP38 process.

Requires

• Go 1.2
• Git
• Mecruial (needed to to checkout go crypto libraries)
• GoConvey for Testing
• Sour-is/bitcoin
• Sour-is/koblitz

Build Instructions

1. checkout source into your $GOROOT/src/ directory and change directory into it.
2. run go get to download dependancies.
3. run go build

Examples

bip38tool encrypt -p 5KJvsngHeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS

BIP38_PASS=secret bip38tool encrypt new

cat keyfile | BIP38_PASS=secret bip38tool encrypt batch

The keyfile is a list of private keys one per line in hex or base58 format.

BIP38_PASS=secret bip38tool decrypt 6PRQ7ivF6rFMn1wc7z6w1ZfFsKh4EAY1mhF3gCYkw8PLRMwfZNVqeqmW3F

Using OpenSSL for key generation

While the tool will use a secure random generator, if you would like to use one that was generated using a different tool that is an option.

If using openssl for the key generation generate a random seed to ensure it has the highest quality entropy. (see: http://crypto.stackexchange.com/questions/9412/)
