I have tried that as well. But the problem here is the decrypted file from the PERL. I was not aware of PERL programming. The solution what was available in the internet will work good when we use the same solution for both encryption and decryption but the problem here is the decrypted file. How you got what i am saying correct? Looking forward for you correct reply. Generating the Random Key in c# The RandomNumber class defined in the.NET Framework class library provides functionality to generate random key. Create the static class with name KeyGenerator. Declare the static readonly three char arrays.
If you need to create packages dynamically, or to manage and execute Integration Services packages outside the development environment, you can manipulate packages programmatically. In this approach, you have a continuous range of options:
Load and execute an existing package without modification.
Load an existing package, reconfigure it (for example, for a different data source), and execute it.
Create a new package, add and configure components object by object and property by property, save it, and execute it.
You can use the Integration Services object model to write code that creates, configures, and executes packages in any managed programming language. For example, you may want to create metadata-driven packages that configure their connections or their data sources, transformations, and destinations based on the selected data source and its tables and columns.
This section describes and demonstrates how to create and configure a package programmatically line by line. At the less complex end of the range of package programming options, you can simply load and run an existing package without modification as described in Running and Managing Packages Programmatically.
An intermediate option not described here is that of loading an existing package as a template, reconfiguring it (for example, for a different data source), and executing it. You can also use the information in this section to modify the existing objects in a package.
Note
When you use an existing package as a template and modify existing columns in the data flow, you may have to remove existing columns and call the ReinitializeMetaData method of affected components.

SYNOPSIS
openssl ciphers [
DESCRIPTION
The cipherlist command converts OpenSSL cipher lists into ordered SSL cipher preference lists. It can be used as a test tool to determine the appropriate cipherlist.
Options
(verbose option) lists ciphers with a complete description of protocol version (SSLv2 or SSLv3; the latter includes TLS) key exchange, authentication encryption and mac algorithms used along with any key size restrictions and whether the algorithm is classed as an 'export' cipher. Note that without the
only includes SSL v3 ciphers.
only includes SSL v2 ciphers.
only includes TLS v1 ciphers.
prints a brief usage message.
is a cipher list to convert to a cipher preference list. If it is not included then the default cipher list will be used. The format is described below.
CIPHER LIST FORMAT
The cipher list consists of one or more cipher strings separated by colons. Commas or spaces are also acceptable separators but colons are normally used.
The actual cipher string can take several different forms.
It can consist of a single cipher suite such as RC4-SHA.
It can represent a list of cipher suites containing a certain algorithm or cipher suites of a certain type. For example SHA1 represents all ciphers suites using the digest algorithm SHA1 and SSLv3 represents all SSL v3 algorithms.
Lists of cipher suites can be combined in a single cipher string using the + character. This is used as a logical and operation. For example SHA1+DES represents all cipher suites containing the SHA1 and the DES algorithms.
Each cipher string can be optionally preceded by the characters !,
If ! is used then the ciphers are permanently deleted from the list. The ciphers deleted can never reappear in the list even if they are explicitly stated.
If
If + is used then the ciphers are moved to the end of the list. This option doesn't add any new ciphers it just moves matching existing ones.
If none of these characters is present then the string is just interpreted as a list of ciphers to be appended to the current preference list. If the list includes any ciphers already present they will be ignored: that is they will not moved to the end of the list.
Additionally the cipher string @STRENGTH can be used at any point to sort the current cipher list in order of encryption algorithm key length.
CIPHER STRINGS
The following is a list of all permitted cipher strings and their meanings:
the default cipher list. This is determined at compile time and is normally ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH. This must be the first cipher string specified.
all ciphers suites except the eNULL ciphers which musti be explicitly enabled. Generate dkim key for domain free.
'high' encryption cipher suites. This currently means those with key lengths larger than 128 bits.
'medium' encryption cipher suites currently those using 128 bit encryption.
'low' encryption cipher suites currently those using 64 or 56 bit encryption algorithms but excluding export cipher suites.
export encryption algorithms. Including 40 and 56 bits algorithms.
specifies 40 bit export encryption algorithms.
56 bit export encryption algorithms.
the 'NULL' ciphers that is those offering no encryption. Because these offer no encryption at all and are a security risk they are disabled unless explicitly included.
the cipher suites offering no authentication. This is currently the anonymous DH algorithms. These cipher suites are vulnerable to a 'man in the middle' attack and so their use is normally discouraged.
cipher suites using RSA key exchange.
cipher suites using ephemeral DH key agreement.
cipher suites using DH key agreement and DH certificates signed by CAs with RSA and DSS keys respectively. Not implemented.
cipher suites using RSA authentication that is the certificates carry RSA keys.
cipher suites using DSS authentication that is the certificates carry DSS keys.
cipher suites effectively using DH authentication that is, the certificates carry DH keys. Not implemented.
ciphers suites using FORTEZZA key exchange, authentication encryption or all FORTEZZA algorithms. Not implemented.
TLS v1.0 SSL v3.0 or SSL v2.0 cipher suites respectively.
cipher suites using DH including anonymous DH.
anonymous DH cipher suites.
cipher suites using triple DES.
cipher suites using DES (not triple DES).
cipher suites using RC4.
cipher suites using RC2.
cipher suites using IDEA.
cipher suites using MD5.
cipher suites using SHA1.
CIPHER SUITE NAMES
The following lists give the SSL or TLS cipher suites names from the relevant specification and their OpenSSL equivalents.
SSL v3.0 cipher suites.
TLS v1.0 cipher suites.
Additional Export 1024 and other cipher suites
Note: these ciphers can also be used in SSL v3.
SSL v2.0 cipher suites.
NOTES
The non-ephemeral DH modes are currently unimplemented in OpenSSL because there is no support for DH certificates.
Some compiled versions of OpenSSL may not include all the ciphers listed here because some ciphers were excluded at compile time.

Include all ciphers except NULL and anonymous DH then sort by strength:
Include only 3DES ciphers and then place RSA ciphers last:
