RSAPadding

Class Overview

RSA padding and unpadding. Format of PKCS#1 v1.5 padding is: 0x00 | BT | PS...PS | 0x00 | data...data where BT is the blocktype (1 or 2). The length of the entire string must be the same as the size of the modulus (i.e. 128 byte for a 1024 bit key). Per spec, the padding string must be at least 8 bytes long. That leaves up to (length of key in bytes) - 11 bytes for the data. OAEP padding is a bit more complicated and has a number of options. We support: . arbitrary hash functions ('Hash' in the specification), MessageDigest implementation must be available . MGF1 as the mask generation function . the empty string as the default value for label L and whatever specified in javax.crypto.spec.OAEPParameterSpec Note: RSA keys should be at least 512 bits long

Summary

[Expand] Inherited Methods

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. final void wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long timeout) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed.
