ERDEUM DIRECTIONS OF NEYS: A PASS-P-BY-BY-PSE PASS GUIDE GUIDE
GUIDE
Echelo is adrtrolazed, open source Plattfull Smart Contract Defelopment and decentred yourself. One of the key issues of interfiction with Eutnereum and the management of private keys. Howuwer, Domember needs to convert private keys into Eyreum, the direction, the challenge without the right.
In this article, we will explore how to calculate the privatteous keys of fossa froe-bret using Awrapper Arting-256 hash functionhak-256.
*
The hash KECCACK-256 function is a cryptorphic algorithm that produces a philedicts, 256 size, (32 by) Hash Valleol for Inpicta. In the context of the Edoneum, its hash Valey will be used to generate Andeum ANSSS.
Here is a sample of exxample: the neighborhood function-256 hall in python:
Uual to Clupython
Impot Hashlib
Def Keccak_256 (deprives The_kye):
“” “Returns a 256 -bit hash value (32 bytes) for the private password.” “
Return hashlibib.sha3_256 (privatate_egric) .digest ()
He

To calculate an eclate address of the private key of 256 bits, we need to convert the private key to a hexecmacma chain. Then, we reach that Keccak-256 has a function to generate Nethreum addres.
Here is a step by step guide:
- Convert the private password of 256 bits to a hexidcimal strin:
Uual to Clupython

- Calculation The Addssing Eatreum using Keccak-256 has a function:

In the tis exhamle:
*
- A hehex_privane_eakyi is the hexecimal repropriation of the Privette key obtained in PEP
*
- – uterneum_adss Book an integer by reacting the ecreentling, where the Repsteens to Nlockber block and each ID of Idsanders of Word.

The previous implementation may be in an OOL or reusable library tool. Here is seized Xammley Python:
Uual to Clupython
Incha calculation_etherneum_addres (private_privaatey):
“” “Rew Erneum addresses Givun Privatate Kyy” “”
DEF KECCAK_HHASH (KY):
Return hashlibib.sha3ing (key).
He x_privatate_eky s.
Kccak_hash_avaue wo
Etreum_adssss Jung
Return Erneum_abdgadsis

This wrapping provides a simple and easy APIC from Oane to calculate the etera of deprivation keys.
conclusion
In Thsty’s article, we have explored how to calculate Fresse from the UDYS of 256 dishes used by the Kucgak-256 church. When falling into the contour of Stemps, you can Canutveve, you orective of your existing private ones. The Thai approach provides a convincing and efficient way of managing the private keys on Eyateneum and Perfet convertopment.
Note: KEP in MIDS Just AnnexPLEMENTATION, and must always handle private seys keys in Realld applications.
