usually, the private key algorithm (called block password) is used to encrypt a data block at a time.
If passwords (such as RC2, DES, TripleDes, and Rijndael) convert N -byte into the output block of encrypted bytes by encrypted.
If to encrypt or unbutton the byte sequence, it must be performed by block.
Because N is small (for RC2, DES, and TripleDes, n = 8 bytes; n = 16 [default value]; n = 24; for Rijndael, n = 32), so you must pay data values greater than n more than N. Crypt by one piece at a time.
cuban jewelry wholesale A private key is a string of randomly extracted numbers. Having and controlling private keys is the fundamental to user control with Bitcoin address. When users traded, they wanted to prove that the funds he used were his own, and he had to sign the transaction with his private key.
