What's the Difference

[Vishal Mahajan]

All,

Can someone explain what's the difference between the following two ways 
of initializing the javax.crypto.Cipher class for encrypting a symmetric 
key:

1) Cipher.init(WRAP_MODE, RSAPublicKey)

2) Cipher.init(ENCRYPT_MODE, RSAPublicKey)

I observe that XMLCipher.encryptKey() method always initializes the 
_contextCipher (javax.crypto.Cipher object) in WRAP_MODE.

Thanks in advance,
Vishal
