| Q.
How secure is SafeCryptor? |
A. SafeCryptor uses the Advanced
Encryption Standard (AES)
algorithm to encrypt the information
with a key strength of 128 bits.
AES is the new industry standard
for symmetric-key encryption and a fast,
well-documented, and rigorously tested
algorithm. Besides, the 128-bit encryption
key is generated from the supplied PC
Unique Key, a unique number based
on the current computer configuration
(hardware, operating system, etc). |
|
|
| Q.
Where can I use SafeCryptor? |
A. SafeCryptor can be used
to encrypt all or part of the contents
of any editable text window, e.g., a
message in your email client or web-based
email, a document in your word processor,
an instant message in your favorite
chat program, etc. |
|
|
| Q.
Can I store the encrypted text to be
decrypted at a later time (e.g., after
weeks, months or years)? |
A. As a general rule, and based
in the fact that:
..."your own computer is your
unique key"...
you or the intended recipient should
never store the encrypted text to be
decrypted at a later time (e.g., after
weeks, months or years) because as the
"unique encryption key" was based on
current computer configuration (hardware,
operating system, etc), if this configuration
changes during this time you or the
intended recipient will NOT be able
to decrypt and recover the information
any more. |
|
|
| Q.
Why inmediately after encrypting some
information using SafeCryptor I cannot
decrypt it back to the original text? |
A. Just because the PC Unique
Key you have used for encrypting
the information does not belong to your
computer, but to the recipient's computer.
Therefore, only the intended recipient
is able to decrypt it. |
|
|
| Q.
If "my own computer is my unique
key", does it mean that all users
who use my computer will be allowed
to read the encrypted information I
receive? |
A. Of course not! Each user will
be assigned his/her own PC Unique
Key even when using the same computer
or different computers with the same
configuration (hardware, operating system,
etc). |
|
|
| Q.
Can I safely communicate my PC Unique
Key using any insecure channel (e.g.
e-mail or chat session) to anyone interested
in sending me encrypted information? |
A. Sure you can! Because knowing
this unique number is not enough, that
is, any information that is encrypted
using it can only be decrypted on the
specific computer where this "unique
encryption key" was issued - your
computer in this case. |
|
|
| Q.
I need to send some encrypted information.
Do I need to ask my recipient(s) to
purchase SafeCryptor? |
A. No, SafeCryptor should
be purchased by the person who needs
to encrypt the information only - you
in this case. Recipients only need to
download and run SafeDecryptor
from:
http://www.gemiscorp.com/english/free/sdecryptor.zip
This FREE version was created
to allow recipients to know their PC
Unique Keys and decrypt the received
information, without needing to purchase
the full product version. |
|
|
| Q.
What are the 'separator lines'? Why
should I include them when sending the
encrypted block to the recipient? |
A. The separator lines clearly
delimitate where the encrypted block
begins and ends (see an example below)
and they are used by SafeCryptor
or SafeDecryptor to properly
decrypt the encrypted text information.

| Q.
I am encrypting a short text or just
a single word. Why do I get a large
encrypted block? |
A. That's because the text information
you encrypt is actually "Rich Text".
For instance, when you encrypt the word:
"SafeCryptor"
you are actually encrypting the string:
"{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl
{\f0\froman\fcharset0 Times New Roman;}}..\uc1\pard
\lang3082\f0\fs24 SafeCryptor}.."
which contains all the necessary character
and paragraph formatting for the given
text. |
