Simplecrypt Python Error

I am using the simplecrypt library to encrypt a file, however I cannot seem to read the file in a way that simplecrypt can decode it. Encryption code: from simplecrypt import encr

Solution 1:

Aha... Minor mistake :-)

According to the docs in the link you provided in your question, the arguments to symplecrypt.encrypt and simplecrypt.decrypt are ('password', text). In your code you've got that inverted ( (text, key) ). You're passing the text to encrypt/decrypt in the first argument and the key in the second. Just reverse that order and will work.

Working example:

from simplecrypt import encrypt, decrypt
defencrypt_file(file_name, key):
    withopen(file_name, 'rb') as fo:
        plaintext = fo.read()
    print"Text to encrypt: %s" % plaintext
    enc = encrypt(key, plaintext)
    withopen(file_name + ".enc", 'wb') as fo:
        fo.write(enc)

defdecrypt_file(file_name, key):
    withopen(file_name, 'rb') as fo:
        ciphertext = fo.read()
    dec = decrypt(key, ciphertext)
    print"decrypted text: %s" % dec
    withopen(file_name[:-4], 'wb') as fo:
        fo.write(dec)

if __name__ == "__main__":
    encrypt_file("test.txt", "securepass")
    decrypt_file("test.txt.enc", "securepass")
