WebSome encryption algorithms require an initialization vector, which is a randomly generated number that is used along with a secret key to encrypt data. This prevents repeated encryption of the same data using the same secret key. The recipient requires this initialization vector to decrypt the message, and hence, is placed in the JWE token. WebSo, if we don't fix the initialization vector, but chose it according to the plain text (or chose the plain text according to the IV), we can get two ( I V, P) pairs which will give the same …

The IV doesn't have to be secret but should be changed for each session. ... The symmetric encryption classes supplied by .NET require a key and a new IV to encrypt and decrypt data. WebApr 19, 2004 · The lower level of WEP encryption uses a 40 bit 10 hex character secret key set by the user and a 24 bit Initialization Vector which is not under user control. Some vendors refer to this level of WEP as 40 bit, others as 64 bit. Either way, theyÂ´re the same encryption level and can interoperate. sickness yellow bile
