How to Generate a Public/Private Key Pair for Use With Secure Shell. Users must generate a public/private key pair when their site implements host-based authentication or user public-key authentication. For additional options, see the ssh-keygen(1) man page. Before You Begin. How to generate the Private Key,Public Key and Secret Key via Bouncy Castle using C#? I have created the keys using online PGP key generator and also via the command line. But my need is to generate the Private Key,Public Key and Secret Key via Bouncy Castle using C#.

X.509 certificates are used to authenticate clients and servers. The mostcommon use case is for web servers using HTTPS.
Creating a Certificate Signing Request (CSR)¶
When obtaining a certificate from a certificate authority (CA), the usualflow is:
- You generate a private/public key pair.
- You create a request for a certificate, which is signed by your key (toprove that you own that key).
- You give your CSR to a CA (but not the private key).
- The CA validates that you own the resource (e.g. domain) you want acertificate for.
- The CA gives you a certificate, signed by them, which identifies your publickey, and the resource you are authenticated for.
- You configure your server to use that certificate, combined with yourprivate key, to server traffic.
If you want to obtain a certificate from a typical commercial CA, here’s how.First, you’ll need to generate a private key, we’ll generate an RSA key (theseare the most common types of keys on the web right now):
If you’ve already generated a key you can load it with
load_pem_private_key()
.Next we need to generate a certificate signing request. A typical CSR containsa few details:
- Information about our public key (including a signature of the entire body).
- Information about who we are.
- Information about what domains this certificate is for.
Now we can give our CSR to a CA, who will give a certificate to us in return.

Creating a self-signed certificate¶
While most of the time you want a certificate that has been signed by someoneelse (i.e. a certificate authority), so that trust is established, sometimesyou want to create a self-signed certificate. Self-signed certificates are notissued by a certificate authority, but instead they are signed by the privatekey corresponding to the public key they embed.
This means that other people don’t trust these certificates, but it also meansthey can be issued very easily. In general the only use case for a self-signedcertificate is local testing, where you don’t need anyone else to trust yourcertificate.
Like generating a CSR, we start with creating a new private key:
Then we generate the certificate itself:
And now we have a private key and certificate that can be used for localtesting.
Determining Certificate or Certificate Signing Request Key Type¶
Certificates and certificate signing requests can be issued with multiplekey types. You can determine what the key type is by using

History
ColdFRusion (2018 release): Introduced named parameters.
ColdFusion 8: Added support for encryption using the RSA BSafe Crypto-J library on Enterprise Edition.
ColdFusion MX 7.01: Added the IVorSalt and iterations parameters.
ColdFusion MX 7: Added the algorithm and encoding parameters.
Parameters
Parameter | Description |
---|---|
string | String to encrypt. |
key | String. Key or seed used to encrypt the string.
|
algorithm | (Optional) The algorithm to use to encrypt the string. The Enterprise Edition of ColdFusion installs the RSA BSafe Crypto-J library, which provides FIPS-140 Compliant Strong Cryptography. It includes the following algorithms:
|
| |
In addition to these algorithms, you can use the algorithms provided in the Standard Edition of ColdFusion. | |
The Standard Edition of ColdFusion installs a cryptography library with the following algorithms:
If you install a security provider with additional cryptography algorithms, you can also specify any of its string encryption and decryption algorithms. | |
encoding | (Optional; if you specify this parameter, also specify the algorithm parameter). The binary encoding in which to represent the data as a string.
|
IVorSalt | (Optional) Specify this parameter to adjust ColdFusion encryption to match the details of other encryption software. If you specify this parameter, also specify thealgorithmparameter.
|
iterations | (Optional) The number of iterations to transform the password into a binary key. Specify this parameter to adjust ColdFusion encryption to match the details of other encryption software. If you specify this parameter, also specify the algorithm parameter with a Password Based Encryption (PBE) algorithm. Do not specify this parameter for Block Encryption algorithms. Use the same value to encrypt and decrypt the data. |
Usage
This function uses a symmetric key-based algorithm, in which the same key is used to encrypt and decrypt a string. The security of the encrypted string depends on maintaining the secrecy of the key.
The following are the FIPS-140 approved algorithms included in the RSA BSafe Crypto-J library that are used by ColdFusion. Some of these are not used with the encrypt function, but are used with other functions:
- AES – ECB, CBC, CFB (128), OFB (128) – [128, 192, 256-bit key sizes]
- AES – CTR
- Diffie-Hellman Key Agreement
- DSA
- FIPS 186-2 General Purpose [(x-Change Notice); (SHA-1)]
- FIPS 186-2 [(x-Change Notice); (SHA-1)]
- HMAC-SHAx (where x is 1, 224, 256, 384, or 512)
- RSA PKCS#1 v1.5 (sign, verify) (SHA-1,SHA-224,SHA-256,SHA-384,SHA-512)
- Secure Hash Standard (SHA-1, SHA-224, SHA-256, SHA-384, SHA-512)
- Triple DES - ECB, CBC, CFB (64 bit), and OFB (64 bit)
Coldfusion Generate Private Public Key Pair List
All algorithms included in the RSA BSafe Crypto-J library are available for use in the Enterprise Edition. In certain cases, you may want to disable some algorithms. To disable the DESX, RC5, and MD5PRNG algorithms, specify the following in the JVM arguments on the Java and JVM page of the ColdFusion Administrator:
Coldfusion Generate Private Public Key Pair For Iphone
-Dcoldfusion.enablefipscrypto=true |
Coldfusion Generate Private Public Key Pair Linux
FIPS-140 approved cryptography is not available if you are running ColdFusion on WebSphere of JBoss.
To use the IBM/Lotus Sametime Instant Messaging Gateway in the Enterprise edition, disable the FIPS-140-only cryptography setting by specifying the following in the JVM arguments on the Java and JVM page of the ColdFusion Administrator:
-Dcoldfusion.disablejsafe=true |
In Standard Edition, for all algorithms except the default algorithm, ColdFusion uses the Java Cryptography Extension (JCE) and installs a Sun Java runtime that includes the Sun JCE default security provider. This provider includes the algorithms listed in the Parameters section. The JCE framework includes facilities for using other provider implementations; however, Adobe cannot provide technical support for third-party security providers.
The default algorithm, which is the same one used in ColdFusion 5 and ColdFusion MX, uses an XOR-based algorithm that uses a pseudo-random 32-bit key, based on a seed passed by the user as a function parameter. This algorithm is less secure than the other available algorithms.
Example
The following example encrypts and decrypts a text string. It lets you specify the encryption algorithm and encoding technique. It also has a field for a key seed to use with the CFMX_COMPAT algorithm. For all other algorithms, it generates a secret key.
