This private key is generated from 1

If i do this other way on this same site, It gives me different result

enter image description here I want a formula to convert This 1 into this private key(5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf) in python Anyone knows formula or python code to do this ?

Using this Python library (I am the author)

>>> from cryptotools import PrivateKey
>>> i = 1
>>> prv = PrivateKey(i.to_bytes(32, ‘big’))
>>> prv.wif()
  • Thanks , Exactly what i needed Aug 10, 2021 at 13:13
  • This code gets compressed key, Is there anyway to get Uncompressed from same way. Thanks Aug 10, 2021 at 14:47
  • The code above is uncompressed. For compressed use prv.wif(compressed=True)

  • It gives me different result for compressed key for example [1]: i.stack.imgur.com/Ydbhn.png This key is 769 But the script give me this key [2]: i.stack.imgur.com/48GFY.png What am i doing wrong What change do i have to do to get KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU74sHUHy8S , from i = 769 Aug 10, 2021 at 19:17
  • I think the brainwallet site is padding to 33 bytes in the last screenshot so replace 32 with 33

If i do this other way on this same site, It gives me different result

Try entering 0000000000000000000000000000000000000000000000000000000000000001 and selecting Hex at the top and Base58check at the bottom.

I want a formula to convert This 1 into this private key (5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf) in python

https://www.google.com/search?q=python+base58check leads to https://pypi.org/project/base58check/ and many others.

Note that these libraries require that your value 1 be expressed as a byte array, not as a single decimal integer.

Remember that what you are seeing is not conversion of a single number into a private key but simply the same number presented in two different representations. That is, two different encodings. Note also that encoding is not encryption.

  • 1 is the same number as 0x01 even though the latter is encoded as hexadecimal.

  • 1 is the same number as 5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf even though the latter is encoded as Base58check.

  • Any idea how can i convert 1 into the byte array and then convert that bye array into the privatekey 5HpHag...... I want to do all of these in python Aug 10, 2021 at 12:20

You can also do it "from scratch" with just hashlib, binascii and base58 modules:

import hashlib, binascii, base58

pkeyhash = "0000000000000000000000000000000000000000000000000000000000000001"

pkeyvbytes = "80"+pkeyhash

firsthash = hashlib.sha256(binascii.unhexlify(pkeyvbytes)).hexdigest()

secondhash = hashlib.sha256(binascii.unhexlify(firsthash)).hexdigest()

createkey = pkeyvbytes+secondhash[:8]

WIF = base58.b58encode(binascii.unhexlify(createkey))


>>> 5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf
