Installation

Use pip to install the crunch-encrypt.

pip install --upgrade crunch-encrypt

Usage for ECIES

This encryption requires two keys:

• a private key for decryption
• and a public key for encryption.

An ephemeral key is also derived from the public key for each file. In order for the file to be decrypted, this ephemeral key must be provided.

Generate a Key Pair

crunch-encrypt ecies key-pair

Encrypt a file

crunch-encrypt ecies encrypt hello.txt hello.txt.enc

[!TIP] To generate a dummy file, do the following:

echo 'Hello World!' > hello.txt

Decrypt a file

crunch-encrypt ecies decrypt hello.txt.enc hello.txt.dec

[!TIP] Use the diff tool to validate the decryption:

diff hello.txt hello.txt.dec
