Convert a list of 64 hex keys to private import format

Question

Is there a python script that i could use to convert a list of private hex keys to there import format in bulk?

How would I go about this..

Could this be adjusted to take a .txt list of hex addresses and convert the to private import format, then print the results to a txt file?

In [1]: import base58
In [2]: hexstring= "00010966776006953D5567439E5E39F86A0D273BEED61967F6"
In [3]: unencoded_string = bytes.fromhex(hexstring)
In [4]: encoded_string= base58.b58encode(unencoded_string)
In [5]: print(encoded_string)

Answer 1

You should consider using this (or a similar) python library to import your keys, as straight conversion from hex to base58 can have a few gotchas:

Check the examples in the README and you should be on your way to making your script.

Answer 2

You can use these little scripts in command line, so you don't have to program a single line (also run in Windows if you have Python), or easily modify them if you want:

For your private key example:

$ ./bitcoin-wif-from-private-key.py 00010966776006953D5567439E5E39F86A0D273BEED61967F6

privkey = 8000010966776006953D5567439E5E39F86A0D273BEED61967F6

For uncompressed public key:
checksum =      02d037e84dee212e14b823a8c9ac01409f6c1504e558d86116a4302d4d68bbdf
key + checksum =        8000010966776006953D5567439E5E39F86A0D273BEED61967F6 02d037e8
bitcoin address =       Sea2qLkneYfbTv29SLY8QvhkAZDxwgDfMuWprqj4b

For compressed public key:
checksum =      021538258480bbb46a846ef24bb2927d24f7c90bf354d76d6da3bd52c47e633d
key + checksum =        8000010966776006953D5567439E5E39F86A0D273BEED61967F601 02153825
bitcoin address =       2xCpo6NCGUimM7o24EqEPic2qXBEDvL6tKGne3Avisv

If you modifiy the script setting this variable to False, only WIF addresses are printed:

VERBOSE = False

(Once you have programmed the desired output) you can make a batch file (.sh in linux, .bat in Windows) with a command line per private key (an editor like Sublime Text for example can edit and paste multiple lines at once, so it's easy) each appending to the a file, and the run this batch file:

./bitcoin-wif-from-private-key.py 1stkey >> mytextfile.txt
./bitcoin-wif-from-private-key.py 2ndkey >> mytextfile.txt
...

---

PS: there're two ways of produce the WIF from a private key (compressed and uncompressed): any of them both will do the job.
