Disclaimer

• Don't trust, verify

  Compare the results of this tool with others. Verify the implementation (and the tests). Decrypt immediately after an encryption to check the passphrase you typed was the one you wanted. Use at your won risk.

• Not recommended

  Use this tool only to decrypt keys you already have. The method of keeping private keys encrypted with bip-0038 standard is not recommended anymore (use mnemonic instead).

Features

• Address

  This tool show the respective address of a decrypted private key in the legacy, segwit-nested and segwit-native formats according to the version prefix of the encrypted private key.

• Custom separator

  Customization of the default separator of information when decrypting.

• Decryption

  Insert an encrypted private key 6P... and passphrase do show the private key represented in hexadecimal and the respective address, public key and wif keys.

• Encryption

  Insert a private key in the form of hexadecimal numbers or wif key and passphrase to show the encrypted private key.

• Generation (elliptic curve multiplication method)

  Insert a passphrase to create an encrypted private key using pseudo-random number generation and elliptic curve multiplication.

• Uncompressed address

  This tool is capable of resulting in uncompressed address (mainly for decryption and retro compatibility, not recommended).

Help

Insert encrypted, hexadecimal or wif private key and passphrase to decrypt or
encrypt accordingly. Insert only passphrase to create an encrypted private key
using elliptic curve multiplication (and pseudo-random number generation).

Usage: encrypt38 [OPTIONS] -p <passphrase> [PRIVATE_KEY]

Arguments:
  [PRIVATE_KEY]  Hexadecimal, wif or encrypted private key
