Ok, I'll try that. Thanks John

>>In using some of the Cryptography routines I am trying to use the GenerateKey() and GenerateIV() methods to allow for creation of Keys and IVs for the encryption process. When this is done, it is needful to store the generated keys in a string representation that can later be reconverted to the byte arrays used for the encryption process.

>>I am having trouble finding the appropriate conversion from byte array to string for storage. I've used several of the encoding methods to convert to a string representation but reconverting to the byte array does not yield the original bytes which causes the encryption process to fail ( catastrophically :-) ).
