I Have Some P7M And P7S Files got from My Client.
I want o Extract Attachments from the Corresponding Files
I am able to decrypt P7M And Extracted Attachments from that eml Files using OpenSSL
but when it come to the case of P7S the decryption method is not working
Is there any one can help to the correct way of decryption format of Openssl

I'm not using command line, merely two separate GUI programs that should functionally work together, but I'm unable to both verify a signed file and decrypt a file sent to me by someone else using Symantec's PGP program and I'm using "GPG Keychain." They have my public key and I have theirs. Any idea why they're not working when they should be?
While using GPG for encryption is it safe to rename the file after it is encrypted or depending on the algorithm used for encryption the file uses the name also for verifying the contents.
You can rename the file without issues. The original filename is safely encrypted inside the file. The filename is never used for decryption in any way.
I have been tasked with duplicating the functionality of SecureZip; namely encrypting and digitally signing a file and then sending via SFTP.
I've been able to put together a java program based on the bouncycastle examples, and have been able to encrypt and decrypt files (with a locally generated PGP key) using this program. However, now I'm trying to implement the digital signature and want to capture the keys used for signing on the AIX system that is running the SecureZip commands.
So when I run the command
pkzipc -listcertificates
I get a response that indicates there are two OpenPGP certificates available for signing. Referring to them using
pkzipc -archivetype=pgp -add -recipient=<PUBLIC KEY RECIPIENT> -certificate=<CERT NAME> -sign=files file.out file.in
allows me to create the encrypted files using this CERT NAME cert. My question is, where? Where are these certificates located? Does AIX have a central OpenPGP certificate location or are these somehow imported into some SecureZip storage location?
Using SecureZip Server Version 14 for AIX
Using AIX 7100-03
I found the certificate location. Evidently there are three locations in UNIX that PKZIPC looks (according to the manual I finally got my hands on):
For public keys:
$PK_OPENGPG_PUBLIC_RING
$HOME/.pgp/pubring.pkr
For private keys:
$PK_OPENPGP_SECRET_RING
$HOME/.pgp/secring.skr
$HOME/.gnupg/secring.gpg
I would like to ask a question about ioncube encryption. I have successfully encrypted a *.conf file.
When I run it, it doesn't seems to be running properly.
How can I encrypt a non-php file? Can you give a step by step process?
All steps taken from the latest ionCube Encoder User Guide for Version 9 and the GUI documentation.
Encrypt files
In the command line encoder, you can create encrypted files with the command
--encrypt "fileselector"
You can chain these together to select multiple files, and use Wilcards as selectors. For example:
ioncube_encoder --encrypt "*.conf" --encrypt "*.xml"
In the GUI you can enter these selectors in the 'Source Tab' in your Project settings, under the 'Non-PHP encryption extensions' label:
Loading encrypted files
Once the files are encrypted, you can read their content by calling the function:
mixed ioncube_read_file(string path [,bool &was_encrypted [,string passphrase] ] ] )
For example, if you encrypted the file foo.conf without passphrase, you can get the content back by calling:
$file_content = ioncube_read_file("foo.conf");
Note: This only works from already encoded files, otherwise the encryption would be useless. Furthermore, encrypted files can only be decrypted by files encoded with the same ionCube Encoder, i.e. if you encrypt your files on Machine 1 and try to decrypt them with files encoded on Machine 2, you won't be able to decrypt the file.
I am new to cryptography, hence I want to ask about my company's requirements.
We are using eToken with RSA support.
I have developed a code that encrypt file with public key and stored it in another file.
Now I want to pass the encrypted file to eToken, and here is my issue.
How can I access the eToken from a Java applet?
Is it right that I have to pass encrypted file to eToken and it will decrypt file for me?
How can I do this?
