Interface sun.security.jsafe.RSAKey

public interface RSAKey
extends Object
RSA public and private keys expose certain information that is needed by applications which use them. That information is exposed through this interface.

Method Index

o getModulusLen()
Return the size of the RSA modulus, in bits.
o isSigningOnly()
Returns true if this key is restricted so that it may be used only for digital signing applications.

Methods

o getModulusLen 
  public abstract int getModulusLen() throws InvalidKeyException
Return the size of the RSA modulus, in bits. This constrains many algorithms using RSA keys. For example, PKCS #1 encryption can only encrypt blocks of up to eleven bytes less than this size, and the size of the encrypted blocks is always exactly this size.

Also, since this modulus length affects the work that's involved in the RSA factoring problem, the modulus length affects various security policies. For example, current US export regulations do not allow use of keys larger than 512 bits for general encryption in exportable applications.

o isSigningOnly 
  public abstract boolean isSigningOnly() throws InvalidKeyException
Returns true if this key is restricted so that it may be used only for digital signing applications.
