Apr 03, 2012 Asymmetric encryption and decryption are relatively resource-intensive, but they provide a higher level of security than symmetric encryption. An asymmetric key can be used to encrypt a symmetric key for storage in a database. For best performance, encrypt data using symmetric keys instead of certificates or asymmetric keys. Re: Failed to install VCenter server v6.5U2 daphnissov Jul 16, 2018 6:23 AM ( in response to Scorpio12138 ) Although you seem to have resolved your issue, it's strongly, strongly recommended that you do not use a Windows-based vCenter. $ begingroup$ PGP is using a Key Derivation to produce a symmetric session key from a passphrase. It has even two modes, it can genrate a randome symmetric key and wrap this with the derived key from the password or it can use the key derived from the password directly.
How to Generate a Symmetric Key by Using the pktool Command
Some applications require a symmetric key for encryption and decryption of communications. In this procedure, you create a symmetric key and store it.
If your site has a random number generator, you can use the generator to create a random number for the key. This procedure does not use your site's random number generator.
Dec 10, 2016 Hello All, happy to see vmware now support to VM encryption with KMIP protocol, only PyKMIP is free solution at this moment, hope to see more article to show to setup and manage PyKMIP in this topic and see vmware contribute more code to. This symmetric key is encrypted by using an asymmetric public key that corresponds to the computer and the user account that is used to run the Report Server service. When you change the user account that is used to run the Report Server service, the report server cannot use the asymmetric public key to decrypt the symmetric key. On Symmetric Encryption with Distinguishable Decryption Failures. Alexandra Boldyreva1, Jean Paul Degabriele2, Kenneth G. Paterson2, and Martijn Stam3 1 Georgia Institute of Technology 2 Royal Holloway, University of London 3 University of Bristol Abstract. We propose to relax the assumption that decryption failures are indistinguishable in security mod.
- (Optional)If you plan to use a keystore, create it.
- To create and initialize a PKCS #11 keystore, see How to Generate a Passphrase by Using the pktool setpin Command.
- To create and initialize an NSS database, see the sample command in Example 4–5.
- Generate a random number for use as a symmetric key.
Use one of the following methods.
- Generate a key and store it in a file.
The advantage of a file-stored key is that you can extract the key from this file to use in an application's key file, such as the /etc/inet/secret/ipseckeys file or IPsec. The usage statement shows the arguments.
- outkey=key-fn
The filename where the key is stored.
- keytype=specific-symmetric-algorithm
For a symmetric key of any length, the value is generic. For a particular algorithm, specify aes, arcfour, des, or 3des.
For FIPS 140-approved algorighms, select a key type that has been validated for FIPS. See FIPS 140 Algorithms in the Cryptographic Framework in Using a FIPS 140 Enabled System in Oracle Solaris 11.2.
- keylen=size-in-bits
The length of the key in bits. The number must be divisible by 8. Do not specify for des or 3des.
For FIPS 140-approved algorithms, select a key length that has been validated for FIPS. See FIPS 140 Algorithms in the Cryptographic Framework in Using a FIPS 140 Enabled System in Oracle Solaris 11.2.
- print=n
Prints the key to the terminal window. By default, the value of print is n.
- Generate a key and store it in a PKCS #11 keystore.
The advantage of the PKCS #11 keystore is that you can retrieve the key by its label. This method is useful for keys that encrypt and decrypt files. You must complete Step 1 before using this method. The usage statement shows the arguments. The brackets around the keystore argument indicate that when the keystore argument is not specified, the key is stored in the PKCS #11 keystore.
Rails generate new master.key 2016. The master key is the only environment key that is now seeded to Heroku. Though I still need this key locally to access the credentials. Then if my computer is stolen both development and production keys are corrupt and can generate a higher risk for my production app.
- label=key-label
A user-specified label for the key. The key can be retrieved from the keystore by its label.
- keytype=specific-symmetric-algorithm
For a symmetric key of any length, the value is generic. For a particular algorithm, specify aes, arcfour, des, or 3des.
For FIPS 140-approved algorithms, select a key type that has been validated for FIPS. See FIPS 140 Algorithms in the Cryptographic Framework in Using a FIPS 140 Enabled System in Oracle Solaris 11.2.

- token=token
The token name. By default, the token is Sun Software PKCS#11 softtoken.
- sensitive=n
Specifies the sensitivity of the key. When the value is y, the key cannot be printed by using the print=y argument. By default, the value of sensitive is n.
- extractable=y
Specifies that the key can be extracted from the keystore. Specify n to prevent the key from being extracted.
- print=n
Prints the key to the terminal window. By default, the value of print is n.
- Generate a key and store it in an NSS keystore.
You must complete Step 1 before using this method. The usage statement shows the arguments.
- label=key-label
A user-specified label for the key. The key can be retrieved from the keystore by its label.

- token=token
The token name. By default, the token is the NSS internal token.
- dir=directory
The directory path to the NSS database. By default, directory is the current directory.
- prefix=directory
The prefix to the NSS database. The default is no prefix.
- Generate a key and store it in a file.
- (Optional)Verify that the key exists.
Use one of the following commands, depending on where you stored the key.
- Verify the key in the key-fn file.
- Verify the key in the PKCS #11 or the NSS keystore.
Alternately, replace keystore=pkcs11 with keystore=nss in the command.
In the following example, a user creates a PKCS #11 keystore for the first time and then generates a large symmetric key for an application. Finally, the user verifies that the key is in the keystore.
Note that the initial password for a PKCS #11 keystore is changeme. The initial password for an NSS keystore is an empty password.
Example 3-2 Creating a FIPS-approved AES Key by Using the pktool Command In the following example, a secret key for the AES algorithm is created using a FIPS-approved algorithm and key length. The key is stored in a local file for later decryption. The command protects the file with 400 permissions. When the key is created, the print=y option displays the generated key in the terminal window.
The user who owns the keyfile retrieves the key by using the od command.
Example 3-3 Creating a Symmetric Key for IPsec Security AssociationsIn the following example, the administrator manually creates the keying material for IPsec SAs and stores them in files. Then, the administrator copies the keys to the /etc/inet/secret/ipseckeys file and destroys the original files.
First, the administrator creates and displays the keys that the IPsec policy requires:
Then, the administrator creates the following /etc/inet/secret/ipseckeys file:
After verifying that the syntax of the ipseckeys file is valid, the administrator destroys the original key files.
The administrator copies the ipseckeys file to the communicating system by using the ssh command or another secure mechanism. On the communicating system, the protections are reversed. The first entry in the ipseckeys file protects inbound packets, and the second entry protects outbound packets. No keys are generated on the communicating system.
Next Steps
To proceed with using the key to create a message authentication code (MAC) for a file, see How to Compute a MAC of a File.
ESXi and vCenter Server support standard X.509 version 3 (X.509v3) certificates to encrypt session information sent over Secure Socket Layer (SSL) protocol connections between components. If SSL is enabled, data is private, protected, and cannot be modified in transit without detection.
All network traffic is encrypted as long as the following conditions are true:
■ | Your firewall is configured for medium or high security. |
Certificate checking is enabled by default and SSL certificates are used to encrypt network traffic. However, ESXi and vCenter Server use automatically generated certificates that are created as part of the installation process and stored on the server system. These certificates are unique and make it possible to begin using the server, but they are not verifiable and are not signed by a trusted-well-known certificate authority (CA). These default certificates are vulnerable to possible man-in-the-middle attacks.

To receive the full benefit of certificate checking, particularly if you intend to use encrypted remote connections externally, install new certificates that are signed by a valid internal certificate authority or purchase a certificate from a trusted security authority. Replacing vCenter Server certificates is described in the vSphere Examples and Scenarios documentation.
If the self-signed certificate is used, clients receive a warning about the certificate. To address this issue, install a certificate that is signed by a recognized certificate authority. If CA-signed certificates are not installed, all communication between vCenter Server and vSphere Clients is encrypted using a self-signed certificate. These certificates do not provide the authentication security you might need in a production environment.

The certificate consists of two files: the certificate itself (rui.crt) and the private-key file (rui.key).
