<title>Decryption</title>

|
|
<p>Decrypting something encrypted to a key in one's secret keyring is fairly straight
|
|
|
|
|
forward.</p>
|
|
|
|
|
<p>In this example code, however, preconfiguring either <codeph>gpg.Context()</codeph> or
|
|
|
|
|
<codeph>gpg.core.Context()</codeph> as <codeph>c</codeph> is unnecessary because there is
|
|
|
|
|
no need to modify the Context prior to conducting the decryption and since the Context is
|
|
|
|
|
only used once, setting it to c simply adds lines for no gain.</p>

<codeblock id="decry-1" outputclass="language-python">import gpg
|
|
|
|
|
|
|
|
|
|
ciphertext = input("Enter path and filename of encrypted file: ")
|
|
|
|
|
newfile = input("Enter path and filename of file to save decrypted data to: ")
|
|
|
|
|
|
|
|
|
|
with open(ciphertext, "rb") as cfile:
|
|
|
|
|
plaintext, result, verify_result = gpg.Context().decrypt(cfile)
|
|
|
|
|
|
|
|
|
|
with open(newfile, "wb") as nfile:
|
|
|
|
|
nfile.write(plaintext)
|
|
|
|
|
</codeblock>
|
|
|
|
|
</p>
|
|
|
|
|
<p>The data available in <codeph>plaintext</codeph> in this example is the decrypted content
|
|
|
|
|
as a byte object, the recipient key IDs and algorithms in <codeph>result</codeph> and the
|
|
|
|
|
results of verifying any signatures of the data in <codeph>verify_result</codeph>.</p>
