This library allows you to get the WIF (wallet import format) from a private ECDSA key and vice versa.
Algorithms are taken from https://en.bitcoin.it/wiki/Wallet_import_format
The library is meant for Python version 3.6
Here's an usage example in the Python shell.
Calculate WIF from private key
>>> import btcwif
>>> priv = "0C28FCA386C7A227600B2FE50B7CAE11EC86D3BF1FBE471BE89827E19D72AA1D"
>>> wif = btcwif.privToWif(priv)
>>> wif
'5HueCGU8rMjxEXxiPuD5BDku4MkFqeZyd4dZ1jvhTVqvbTLvyTJ'
Calculate private key from WIF
>>> priv1 = btcwif.wifToPriv(wif)
>>> priv1
'0c28fca386c7a227600b2fe50b7cae11ec86d3bf1fbe471be89827e19d72aa1d'
Check if WIF is positive to checksum
>>> btcwif.wifChecksum(wif)
True
>>> wif1 = "6HueCGU8rMjxEXxiPuD5BDku4MkFqeZyd4dZ1jvhTVqvbTLvyTJ" # invalid WIF
>>> btcwif.wifChecksum(wif1)
False
Trying to calculate private key from invalid WIF
>>> btcwif.wifToPriv(wif1)
