X509BasicConstraints

public X509BasicConstraints(boolean cA)

Creates a new X509BasicConstrains objects with the specified value for cA. This indicates if the certificate is a CA-certificate. This Extension is by default set to non-critical according to RFC 5280.

Parameters:

cA - indicates if the certificate belongs to a CA.

X509BasicConstraints

public X509BasicConstraints(int pathLenConstraint)

Creates a new X509BasicConstrains objects with pathLength limited to the specified value. Note that cA is always set to true if a pathLength is specified. This Extension is by default set to non-critical according to RFC 5280.

Parameters:

pathLenConstraint - the maximum length of a certification Path

X509BasicConstraints

public X509BasicConstraints(mybouncycastle.org.bouncycastle.asn1.ASN1Sequence a_extension)

Creates an new X509BasicConstraints object from a BouncyCastle ASN1Sequence

Parameters:

a_extension - the extions as ASN1Sequence

Method Detail

isCA

public boolean isCA()

Returns:

if the certificate belongs to a CA

getPathLengthConstraint

public int getPathLengthConstraint()

Returns:

the maximal length of a certificate that is build from this certificate to an end entity

getName

public java.lang.String getName()

Description copied from class: AbstractX509Extension

Returns the human-readable name of this extension.

Specified by:

getName in class AbstractX509Extension

Returns:

"BasicConstraints"

getValues

public java.util.Vector getValues()

Description copied from class: AbstractX509Extension

This method returns all values of this extension in separated String objects. The values should be human readable.

Specified by:

getValues in class AbstractX509Extension

Returns:

a Vector containing the values for cA and pathLenConstraint as human readable Strings.
