The EC (Elliptic Curve) Public Key Hash Factory is a simple implementation to generate a SHA-256 hash of a uncomrpessed EC Public Key. Implemented purely in Python, released under the Apache license. You can use the tool easily via command line without being an openssl or EC expert.

-k or -key: uncompressed hex formated public key, e.g "04ad2d126c3f8f85bf5796f6..." -u or -unformattedkey: uncompressed hex unformated public key, e.g "04:ad:2d:12:6c:3f:8f:85:bf: 57:96:f6:..."

Supported EC curve:

• NIST256p

Uncompressed format:

The most common formatting specified in PKIX standards. Specified in X9.62 and SEC1 standards. The only difference between it and :term:raw encoding is the prepending of a 0x04 byte. Thus an uncompressed NIST256p public key encoding will be 65 bytes long.

This library is available on PyPI, it's recommended to install it using pip:

pip install ecdsa or pip install -r requirements.txt
