What it is way most best for causing bash script run (as root) of time mailbox created (lda_mailbox_autocreate)? I use dovecot 2.3.4.1 in Debian 10. And I use of mail-crypt-plugin https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ I setup mail-crypt for requiring user encrypted EC key (mail_crypt_require_encrypted_user_key = yes). I want for passphrase encrypt EC key using client

Howdy. I have a application I'm developing where I need to encrypt the data inside an OGG stream. I will be using a regular block cypher (AES, or others... configurable); and I would like to encrypt the pages in an OGG stream. I'm thinking that if I sit my decrypter in between the reading application and the encrypted file, you should be able to use all the normal seeking

Hi, I have an application where I want to be able to encrypt large amounts of text before storing them to my DB (MySQL Text field - might be switched to a Blob). I have an idea of how to do this, but was wondering what the general consensus is within the community regarding the issue. I have come across a couple different plug ins/gems (Stringbox, EzCrypto), but am wondering what other people

Hi Gerhard, This is not exactly true. CTR modes have the length field encrypted. etm MAC modes and AES-GCM have the length field in cleartext. CBC is dangerous because the length field is encrypted with CBC. aes128-ctr + hmac-sha256 doesn't have any known vulnerability and encrypts the packet length, but uses the bad practice of e&m. chacha20-poly1305 encrypts both payload and packet

I just want to encrypt a string submitted through a form before saving it to the DB. And then decrypt it again when I need to retrieve and use it. Im trying to use the OpenSSL::Cipher library. I have the following module for encryption/decryption [code] require ''openssl'' module AESCrypt # Decrypts a block of data (encrypted_data) given an encryption key # and an

Do you see a use for an IMAP proxy where the proxy would be able to execute hooks which modify mail contents, such as transparent encrypting/decrypting mails, or maybe some virus-filtering? It would need at least some kind of IMAP command/reply parsing capabilities, so it might be able to do all kinds of other things. Maybe one potential use case would be Cyrus Murder-like proxying to multiple

I've successfully implemented the mail_crypt plugin on v2.2.27 and it's working like a champ, but some of our administrative operations require access to Maildir messages in plaintext. I've found numerous threads detailing help with mail_crypt setup, but none of my research has yielded a method of decrypting the stored messages. Relevant plugin config: mail_crypt_curve =

I am pondering the possibility of encrypting/decrypting some fields in a SQLite backend on-the-fly. The point of the message is not security, I know that''s broken, but whether there''s a technique that provides on-the-fly save/read filters. Of course the solution would need to work transparently in joins, so user.posts.last.title would do the right thing if title

Anyone know of a good (fast) way to encrypt/decrypt uploaded files in RoR? I''ve seen this project: http://ezcrypto.rubyforge.org/ but it only seems to encrypt strings and such. I need to encrypt files once they are uploaded, then decrypt them when they request the file back. Any ideas? Thanks, Mark -- Posted via http://www.ruby-forum.com/.

what i have done is as follows password = Digest::SHA1.hexdigest("#{salt}:#{password}") pass1 = Digest::SHA1.hexdigest("#{salt}:asdfgh") pass2 = Digest::SHA1.hexdigest("#{salt}:asdfgh") pass3 = Digest::SHA1.hexdigest("#{salt}:qwerty") puts pass1==pass2 puts pass1==pass3 This works fine but i need to get the decrypted password how can i get it any help is

Hello, I'm looking to use the new 'samba-tool user getpassword' or 'samba-tool user syncpasswords' for syncing to an OpenLDAP server. I've configured the 'password hash gpg key ids' in smb.conf. Everything appears to be working fine, except the plaintext passwords returned from samba-tool user getpassword --decrypt-samba-gpg are different. Do the returned values

Just to be clear, if at any point your VPS has access to the plaintext mail (or keys that decrypt mail), then the VPS provider could access your decrypted mail. To make it unfeasible

This was posted not too long ago on sci.crypt... Enjoy... I think the most relevant information is near the top, but it''s all quite good... :-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- There is no intrinsic difference between algorithm and data, the same information can be viewed as data in one context and as algorithm in another. Why then do so many people claim that encryption algorithms

Hey folks- If I wanted to distribute my code to users that would run the code on their own machine, how could I go about encrypting the source to run on a user''s machine? PHP has the Zend Encoder among others, I believe. Is there anything similar for Ruby? Jake -- Posted via http://www.ruby-forum.com/.

Hi, One of the problems we are facing is secure storage of passwords (database, bestcrypt, other applications/systems, ) and availability within users' scripts (perl, python, ...) or applications (Java, C, ). I'm sure that there are quite a few people who are facing the same issue and there are quite a few home made solutions, such as password obfuscators and/or solutions based on the

Hi, There was a discussion a few months ago about a plugin for encrypting email before it hit the disk on the server, and doing transparent decryption while serving data to the client, see: http://www.dovecot.org/list/dovecot/2009-July/041262.html We have a client/user who is interested in such a plugin, and I was wondering if there has been any progress on it yet. In our particular case,

Colleagues, I have an unusual problem; I am wondering whether anyone has dealt with it and found a solution. I have a script that needs to be encrypted. R will then be run on the script. There are various means to decrypt the file, some of which leave the decrypted code on the hard drive for an excessive period. One means that I have considered to deal with this is the following
