Preparation of the private key, which is assigned to a coinbase-multi-sig-sig resorer address
When creating a multi-sig safe for Coinbase, you will receive two important information: a master public key in BIP32 Extended format and a private key in WIF format (WIF format). In this article we guide you through the process of extraction of the private key, which is assigned to your coinbase-multi-sig-sig-resoration address.
Understand the Master Public Key
The Master Public Key is a 24-byte sign that contains private keys for several addresses. The format of this key is located in the extended BIP32 format, including:
- A public master key (256-bit number of Ganz)
- A higher-level fingerprint (128-bit hexadecimal string)
- A children’s index (2-4 bytes that represents the number of children)
The overarching fingerprint and the subordinate index are used to identify every address in the key. The 24-byte master Public Key is divided into two parts: The first 20 bytes represent the private keys for several addresses, while the next 4 bytes contain additional information on these addresses.
Give the private key from the Master Public Key
To extract the private key that is assigned to your Multi-Sig-Sig resorial address of your coin base, follow these steps:
- Convert the Master Public Key to Hexadepimal : Use a hex editor or online tool (e.g. its hexadecimal representation.
- ** Remove the overarching fingerprint and the subordinate index. Remove these two parts from the hexadecimal string.
- Convert the resulting substring to WIF format : Use a WIF-Parser or online tool (e.g. the remaining 16 bytes of the hexadecimal display in WIF notation.
Example
Let’s assume your public key is:
`
0x1234567890abcdef0123456789abcdef
`
If you remove the overarching fingerprint and the children’s index, you will receive:
`
Abcdef0123456789abcdef
`
If you convert this substring into a WIF format with a parser or online tool, you will receive the private key in WIF notation.
Example of private keys
The resulting private key in WIF format could look like this:
`
1234567890abcdef
`
This is only an example of how you can derive the private key that is assigned to your coinbase-multi-Sig-Sig-Resor address. Remember that the private key should never be saved publicly because it can be used for malicious purposes.
Diploma
The derivation of the private key, which is assigned with a Coinbase-Multi-Sig-Resor address, requires a certain basic knowledge of the cryptography and briefing formats in public. If you take these steps, you can extract the private key from your public key from the master and unlock your assets to coin base. Remember to keep your private keys safe to prevent unauthorized access to your means.
