Ethereum: PEM format for ECDSA

When working with cryptographic keys, including deformations for the Ethereum network, it is necessary to understand how to format them safely. One of the important aspects of key formatting is the use of public encryption algorithms (PKE), such as the elliptical curve algorithm of digital signatures (ECDSA).

In this article, we will look more detail at PEM format and its use in ECDSA for Ethereum.

What is the PEM format?

The PEM format (quite Easy Mail) is a widely used standard for coding public-private keys. It is based on the ASCIIIA character set and uses a simple syntax based on the text to represent cryptographic keys.

Key ECDSA formats

ECDSA keys are usually displayed as a pair of bytes that can be encoded in PEM format using the following format:

`

—— start the ECDSA private key —–

Miulbgkqhkig9w0baqaqaasfaasfgtwjl6u4yzz/…

—— end ecdsa private key —–

`

Here is the fall of each part:

• `-------- Stress' indicates the beginning of the public key block.

• Ecdsais the name of the PKE algorithm used (in this case the elliptical digital signatures algorithm).

• Private key 'codes for a private key in PEM format. Bytets are prefixes from, which indicate that they are part of the ECDS signature.

• The following line is a control sum that confirms data integrity.

private key format

The private key is usually shown as a chain that can be encoded in PEM format:

—— start the ECDSA private key —–

Miulbgkqhkig9w0baqaqaasfaasfgtwjl6u4yzz/…

`

This format contains the following elements:

• `-------- Stress' indicates the beginning of the public key block.

• -Ecdsa-‘There is the name of the PKE algorithm used (in this case ECDSA).

• `Private key 'codes for a private key in PEM format.

Public key format

The public key is usually represented as:

—— Start the public key —–

…

—— Public Key End —–

`

This format includes:

• `-------- Stress' indicates the beginning of the public key block.

• -separates public and private keys.

• The following poem is the public key itself, which can be encoded in PEM format:

… public_key_here …

`

Working with the PEM format in Python-Ecdsa

During cooperation with Ecds for Ethereum, you will have to import the “Ecds” library and use its functions to work with private and public keys. Here is an example of the source of the code, which shows how to cod a private key in PEM format:

`Python

From the signature of the ECDSA import

From Cryptograph.hazmat. Primitive Import Serialization

Generate a new private key

Private_key = signing.signingkey.Generation ()

PEM private key code

Pem_private_ky = private_key.to_string (). Enkoduj ()

Print (pem_private_key)

Load the private key from the file (in PEM format)

Private_key_from_file = Serializal.lam_pm_private_key (

Pem_private_ky,

Password = none,

Backend = "Secrets"

)

Decorate loaded private key in PEM format

Loaded_private_key = private_key_from_file.to_strring (). Decod ()

Print (load_private_key)

This code scrap generates a new private key, coded in PEM format using to_string () and prints the output. Then load the private key from the file (in PEM format) using Load_PEM_PRIVATE_KEY () and decoded the loaded key key.

Application

In this article, we examined the PEM format and its use in ECDSA for Ethereum. Understanding how to encode private and public keys in PEM format, you can safely store and transfer cryptographic keys to your Ethereum projects. When working with private keys, always use a safe password or verification mechanism to prevent unauthorized access.
