I am completely new to bitcoin. My question is how do you convert an uncompressed key to an extended bip32 key? Are there any tools that do that? Thank you

  • They have different use cases. A public key is for receiving sending on, an extended key is for deriving more keys from. Why do you need to convert one into the other, as opposed to creating a new one, for example? – Pieter Wuille Nov 7 '16 at 17:29

With "uncompressed key" you probably refers to an uncompressed public-key.

An extended public-key has additional informations (next to the compressed public-key itself). You can get the pure compressed public key from an extended public key, but not vice-versa.

  • depth (in the hierarchy)
  • child-index
  • chaincode (the hierarchal link)
  • fingerprint (first 4 bytes of the keyId [ripemd(sha256())])
