I'm trying to encode a Protoshares wallet address in raw format as explained in the Bitcoin wiki to Base58 format.
Protoshares addresses start with P (version number 56).
I have given the raw address from the transaction. It looks like that:
028401a2e512b1b91b882ee1c9291cd407c10916bf791662f7189c9c805643e51c
Now I've followed the guide step-by-step from the wiki and my ruby code looks like that:
# 1 - Take the corresponding public key generated with it (65 bytes, 1 byte 0x04, 32 bytes corresponding to X coordinate, 32 bytes corresponding to Y coordinate)
sender = '028401a2e512b1b91b882ee1c9291cd407c10916bf791662f7189c9c805643e51c'
# 2 - Perform SHA-256 hashing on the public key
sender = Digest::SHA256.new.update(sender)
# 3 - Perform RIPEMD-160 hashing on the result of SHA-256
sender = Digest::RMD160.new.update(sender.to_s)
# 4 - Add version byte in front of RIPEMD-160 hash (0x00 for Main Network)
sender = '00' + sender.to_s
# 5 - Perform SHA-256 hash on the extended RIPEMD-160 result
checksum = Digest::SHA256.new.update(sender.to_s)
# 6 - Perform SHA-256 hash on the result of the previous SHA-256 hash
checksum = Digest::SHA256.new.update(checksum.to_s)
# 7 - Take the first 4 bytes of the second SHA-256 hash. This is the address checksum
checksum = checksum.to_s[0,8]
# 8 - Add the 4 checksum bytes from point 7 at the end of extended RIPEMD-160 hash from point 4. This is the 25-byte binary Bitcoin Address.
sender += checksum
This seems to work well so far. My current result looks like that:
0073eb40b21b02c08e93f6ef1bec5828763ac89e456c2f6fec
But now I'm stuck. I'm using the base58 gem by dougal and trying to finally encode the address:
# 9 - Convert the result from a byte string into a base58 string using Base58Check encoding. This is the most commonly used Bitcoin Address format
sender = Base58.encode(sender)
But I get the following issue:
/path/to/base58.rb:23:in `int_to_base58': Value passed is not an Integer. (ArgumentError)
Of course it's not an integer. Did I screwed up with data types here? What to do to get this working correctly?
Thanks!
