Implementation of Blowfish encryption

Managed to encrypt/decrypt strings using the blowfish algorithm rather succinct but have a question which, for some reason, cannot overcome and understand.

The encryption algorithm uses 64-bit blocks, so that two letters in the plaintext are assigned to unsigned long integer subsequent enc...

See below:

int blowfish_encrypt_buffer (blowfish_context_t * ctx, char *, unsigned int, unsigned long bufferlen * enc) {}
unsigned int i;
for (i = 0; i< bufferlen;="" i+="">
ENC [i] = clear text [i];
ENC [i + 1] = clear text [i + 1];
blowfish_encryptblock (ctx, enc [i], & enc [i + 1]);
}

Return i;
}

the output is the painting of the CNE is I long element.

So far so good. If I use enc to decipher, it works fine:

int blowfish_decrypt_buffer (blowfish_context_t * ctx, unsigned long * cryptext, unsigned int bufferlen, char * plaintext) {}
unsigned int i = 0;

for (i = 0; i< bufferlen;="" i+="2) ">
blowfish_decryptblock (ctx, & cryptext [i], & cryptext [i + 1]);
clear text [i] = cryptext [i];
clear text [i + 1] = cryptext [i + 1];
}
clear text [bufferlen] = '\0 ';
Return i;
}

Now if I want to store the encrypted data - an array of unsigned long, in a string, it seems very practical to use the hexadecimal string:

This loop running and visualization of the chain are nice:

for (int i = 0; i)<>
sprintf (Line, "%x", enc [i]);
SetCtrlVal (bpanel, BPANEL_CRYPTEXT, line);
}

It looks like this channel here: 6441696d2d6e615073736f7764723231033...

The problem is that when I want to reveerse this, I can't sscanf the string in long unsigned as it comes. Could not find the settings of fortmatting or any other way to do it even if my life depends on it. :-(

Thank you! This seems to be the solution!

Out of Blowfish Encrypt() differs from encryption Blowfish in PHP and other languages

I need to display the result of an encryption hex blowfish to an external API.
The result of encrypting (myText, key, "BLOWFISH", "HEX") give me a value that I can decipher perfectly in coldfusion, but apparently not the same value that you would get if you ran the same encryption (blowfish, hex) using PHP or Java.
Basically, I'm trying to make the outcome of
Encrypt (myText, key, "BLOWFISH", "HEX")
matches what you get using this tool:
http://webnet77.com/cgi-bin/helpers/Blowfish.pl
This tool seems to output the result that would be generated by php and expect the API.
I don't know why the result is different or what options to get change for Coldfusion to generate the correct value.

I tried the variable myText with null characters to fill so the length is a multiple of 8 of filling (you can use URLDecode ("%00") instead of char (0) as the null character, because char (0) does not actually increase the length of the string). But this does not seem to have much effect.

If someone can make the result of coldfusion blowfish encryption correspond to what you get using this tool above, I would be really grateful.

Still no idea why encryption Blowfish of Coldfusion is different, but here is the code for the use of java in case someone else runs into the same issue:

Just to follow up, it turns out that the essential needs of CF in base64 format (and have a valid key length) to achieve the same result of CF + Java. (I hate it when it's something as simple as that... ;-)

<-cfset mytext="whatever">

cfEncrypted = #cfEncrypted #.

javaEncrypted = #javaEncrypted #.

Implementation of mail encryption

Currently, I have my own mail server implemented using OS X Server El Capitan. I can send and receive e-mails. I can send email signed myself. I can't send emails encrypted to myself. I heard El Capitan has bugs with it, but before I start trying workarounds (for example Re: e-mail encryption does not work in Apple Mail, please Help!), I want to make sure I'm doing even the normal procedure on the right. I don't see that it documented anywhere. My goal is to sign certificates for a group of people, I work with we all send it encrypted and signed e-mails.

I created my own CA with the Certificate Wizard and made my computer to her trust. I then created a certificate using the authority. I guess that this certificate includes the private key, that I need for the decryption and public key, I need for encryption, correct? I restarted the post. What is this good?

In Keychain Access, here is the certificate on the top and the authority for the background:

My client, I test with that runs El Capitan (10.11.1).

I managed to reproduce this problem.

It seems that Mail in El Capitan fails incorrectly show that a message is encrypted, if they are encrypted. However, the message is encrypted, because if I find out the same email in Mail in Yosemite he shows as encrypted. Shows mail in El Capitan correctly e-mail messages that are signed only signed.

So it seems to be more a cosmetic problem since it is encrypt emails.

Note: Mail correctly automatically decrypts the email that you can see its content which, combined with the encryption tag missing shows it is not encrypted, but it is.

You can check this by saying Mail to show the raw message source and you'll see everything, it is coded.

I recommend that declare you it as a bug to Apple. There have been other people indicate a similar problem although they like you I think were more under the encryption of print was not the case. It is disappointing that this bug still exists in 10.11.5.

implement voice strong & encryption of text does not leave U$ A spy and see adaptation go like a rocket

I despise having toms capable advanced read and listen to everything I do. If you put in the encryption without a door back door, this operating system is spreading at the speed of light. Also include a way to say to people if the federal Government make you give them access but with open source, many people can see if this happens.

XTEA encryption problems

I'm trying to implement the XTEA encryption for a project, but the values that I receive does not correspond really. Is there a known problem with this implementation

http://www.NI.com/white-paper/7520/en/

I managed to solve the problem. The encryt implementation, mentioned in vi is false, and all you have to do is to remove the forloop and send data directly key.

(Redirected) Upgrade Windows 10 blocked by a Dell data encryption

I've implemented the Protection/encryption of Dell on the c: / drive of my laptop Latitude 5400 series age of 30 months, by end-2014. I disabled this same encryption mid-2015, because it alters its overall performance for laptop too. Encryption console shows my C: / drive now as "not provisionsed.

Now, I tried (many times) to upgrade my OS Win 7 Pro to win 10 via Microsoft current offers "free upgrade". However, the upgrade is blocked, each time, by encrypting data Dell, according to the report of failure of upgrade to win 10. Doubly frustrating! Is there a hope to solve this? Microsoft reminds me of Dell. Or else, I'll just sit and stay with Win 7, until this laptop is replaced later?

BIS is encrypted push?

Just a little question because I can't find right now: BIS push is encrypted or do you have to add an additional encryption layer in the payload?

Hi, I've heard talk about Devcon 2010 registered, DEV01-Push or do not push content delivery to the customer.

relationship of speaker/developer 45:28 minutes say the content is not encrypted. If the information is very sensitive, you can implement the own encryption key.

Authentication Radius Cisco with Windows NAP with encrypted authentication

I need authentication radius configuration for Cisco IOS devices for device management. My radius server is on Windows 2008 R2.

Can I implement this with encrypted authentication? In the attached diagram, can what protocol I use for encrypted authentication?

According to some sites, we need activate authentication in clear text. All those put in place secure as MSCHAP authentication?

Hello

You activate the text authentication (PAP) clear. Don't forget Ray sends the username in clear but encrypts the password. You can confirm this take a wireshark capture. You will also get the RADIUS encryption using a key to Ray long and complex.

If you want to encrypt the user name and password, then you would use GANYMEDE

Thank you

VPN question on encryption

Hi all

I am currently studying my CCNA to the University and we are doing a group project and must implement a vpn encrypted tunnel. It's a lab environment that is the reason why ports fast ethernet are used for the wan between sites link. Our tunnel works as we only eigrp ajacency when the tunnel is enabled, but is not encrypt the traffic. I pasted the config for both routers below in the hope that someone will spot the problem etc. of the missing parameter. Thanks in advance:
