1 | + | Hello Friend, |

3 | This is an extremely easy way for Mac users to back-up a legally purchased DRM PDF file | |
4 | so you may access it if you lose your password/key or it is no longer supported by ADE software. | |
5 | Please do not pirate electronic book material. | |

7 | After spending no less than 10 hours trying to accomplish the above using Python and PyCrypto, | |
8 | and "ineptkey", "ineptepub", and "ineptpdf" files, I was unsuccessful. Not that there is anything | |
9 | wrong with those applications, I just kept getting an error message when I tried to "decrypt" a file | |
10 | with the extracted key. Then a possible solution occurred to me when I finally took a break and I was | |
11 | in the shower. I tried it, and it worked in about one minute! | |

13 | 1) Right-click on your legally purchased DRM PDF file. | |
14 | 2) Choose "Open With" and then "Preview". | |
15 | 3) Enter your password/key. | |
16 | 4) From "File", choose "Save As". | |
17 | 5) Enter a slightly different name for your back-up copy. | |
18 | 6) Save it as a PDF without selecting the "Encryption" option. | |
19 | 7) You may now open your back-up copy with a program that reads PDF's without a password. | |

21 | 16 "For God so loved the world that he gave his one and only Son, that whoever believes | |
22 | in him shall not perish but have eternal life. 17 For God did not send his Son into the world | |
23 | to condemn the world, but to save the world through him. 18 Whoever believes in him is not | |
24 | condemned, but whoever does not believe stands condemned already because he has not believed in | |
25 | the name of God's one and only Son. 19 This is the verdict: Light has come into the world, | |
26 | but men loved darkness instead of light because their deeds were evil. 20 Everyone who does evil | |
27 | hates the light, and will not come into the light for fear that his deeds will be exposed. | |
28 | 21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what | |
29 | he has done has been done through God." John 3:16-21 (New International Version) | |
