python - How to get Bitcoin address from pubkey_hash ...

Bitcoin would have worked by just using the RIPE hash alone and not the SHA hash first, but the creators were slightly worried because there is a relationship between the elliptic curve and RIPEMD160. While nobody knows if that relationship is useful or if they can prove anything meaningful with it, the Bitcoin creators didn’t want to run the risk, and a simple solution was to apply SHA-256 ... The algorithms used to create a bitcoin address from a public key are Secure Hash Algorithm (SHA) and RACE Integrity Primitives Evaluation Message Digest (RIPEMD), in particular, SHA256 and RIPEMD160. From the public key K it is calculated first the hash SHA256 and then the hash RIPEMD160, generating a 160-bit number (20-byte).

Messing with Bitcoin Keys and AddressesA bitcoin vanity address on the other hand, which is supposed to be personal, the RIPEMD-160 hash function to produce a bitcoin address.Check. Bitcoin uses both SHA-256 and RIPEMD-160 hashes. Most often a double-round SHA-256 is used, but for address generating, RIPEMD-160 is used because it generates a shorter hash value. RIPEMD-160 has ... I found that I had to change the import lines for util to import Crypto.Hash.RIPEMD as RIPEMD160. – Appleman1234 Jul 20 '14 at 16:00 Ubuntu 12 with Python 2.x – George Jul 20 '14 at 16:53
