Hi,

Firstly thanks for reading. I am not an python coder but I have been ask to encrypt some emails and I have incredible slow performance. I have googled the parts to get the script going but I am estimating a week before the encryption is finished. can some help me out


pii_email.txt has 11 million email address

import binascii, hashlib
salt = 'xxxxxxxxx'


print "Opening the file..."
target = open('HASHED_EMAILS.txt', 'w')
print "Truncating the file.  Goodbye!"
target.truncate()
with open('pii_emails.txt') as f:
    for line in f:
#        print(line.rstrip('\n'))
#        print('x')
#        print(binascii.hexlify(hashlib.pbkdf2_hmac('sha256', line.rstrip('\n'), salt, 100000)))
        target.write(binascii.hexlify(hashlib.pbkdf2_hmac('sha256', line.rstrip('\n'), salt, 100000)))
        target.write("\n")

print "And finally, we close it."
target.close()
