Generate new DSA Key from OpenSSL Parameters File

See more DSA Examples

Generates a new DSA key from an OpenSSL-created parameters file (DER and PEM formats supported). Examples of using OpenSSL to create parameter files are shown here:

openssl dsaparam -outform DER 1024 <  seedData.txt >dsaparam.der

openssl dsaparam 1024 < seedData.txt >dsaparam.pem

// To generate a key from PEM, call GenKeyFromParamsPem 
// (for an in-memory PEM string) or GenKeyFromParamsFilePem
// for a PEM file.

// The public and private keys may now be exported to PEM, DER,
// and XML formatted files.

// First for the public key...
// The public key never needs to be encrypted.

// Save the public key in PEM format:
ls_PemStr = loo_Dsa.ToPublicPem()
// This example will not check the return value of SaveText...
li_Success = loo_Dsa.SaveText(ls_PemStr,"dsa_pub.pem")

// Save the public key in DER format:
li_Success = loo_Dsa.ToPublicDerFile("dsa_pub.der")

li_BPublicOnly = 1
// Save to XML
ls_XmlStr = loo_Dsa.ToXml(li_BPublicOnly)
li_Success = loo_Dsa.SaveText(ls_PemStr,"dsa_pub.xml")

// ------------------------------------
// Now for the private key....
// ------------------------------------

// Unencrypted PEM:
ls_PemStr = loo_Dsa.ToPem()
li_Success = loo_Dsa.SaveText(ls_PemStr,"dsa_priv.pem")

// Encrypted PEM:
ls_PemStr = loo_Dsa.ToEncryptedPem("myPassword")
li_Success = loo_Dsa.SaveText(ls_PemStr,"dsa_privEncrypted.pem")

// DER:
li_Success = loo_Dsa.ToDerFile("dsa_priv.der")

// XML:
