Method Details

getAlgorithm

public String getAlgorithm()

setAlgorithm

public void setAlgorithm(String algorithm)

getKey_size

public int getKey_size()

setKey_size

public void setKey_size(int key_size)

setValidity

public void setValidity(int validity)

getCertificateName

public String getCertificateName()

setCertificateName

public void setCertificateName(String certificateName)

setCertificateSN

public void setCertificateSN(long certificateSN)
                      throws SwitchToDefaultParamsException

Throws:

SwitchToDefaultParamsException

computeRandomSerialNumber

public static BigInteger computeRandomSerialNumber()

setOwnerFDN

public void setOwnerFDN(String ownerFDN)

computeKeyPair

public static KeyPair computeKeyPair(String algorithm,
 int keySize)
                              throws NoSuchAlgorithmException

Generate and Return a key pair.

If this KeyPairGenerator has not been initialized explicitly, provider-specific defaults will be used for the size and other (algorithm-specific) values of the generated keys.Our People

This method will computes and returns a new key pair every time it is called.

Returns:

a new key pair

Throws:

NoSuchAlgorithmException - if the algorithm String not match with the supported key generation schemes.

generateCertificateKeyPair

public void generateCertificateKeyPair()
                                throws NoSuchAlgorithmException,
SwitchToDefaultParamsException

recompute a new key pair FOR INTERNAL OSelfSignedCertificate class USE.

This method is functionally equivalent to computeKeyPair(this.algorithm,this.key_size). It uses the value pair (DEFAULT_CERTIFICATE_ALGORITHM,DEFAULT_CERTIFICATE_KEY_SIZE) if the setted fields are not valid.

Throws:

NoSuchAlgorithmException - if the algorithm String not match with the supported key generation schemes.

SwitchToDefaultParamsException
