class AESMBS
class, Encryption and Hash, MBS REALbasic Util Plugin (E4), class AESMBS, Console safe, Plugin version: 4.1, Mac OS X: Works, Windows: Works, Linux x86: Works, Feedback.

Function: A class for AES encryption.
Example: 
dim a as AESMBS
dim key as MemoryBlock
dim data as MemoryBlock

key=NewMemoryBlock(20)
key.CString(0)="Hello World!1234" // 16 byte key for 128bit

a=new AESMBS

if a.SetKey(key, 128) then
  
  data=NewMemoryBlock(20)
  data.StringValue(0,16)="Hello World!"
  MsgBox "Before: "+data.StringValue(0,16)
  a.Encrypt(data)
  MsgBox "After encryption: "+data.StringValue(0,16)
  a.Decrypt(data)
  MsgBox "After decryption: "+data.StringValue(0,16)
else
  MsgBox "Failed"
end if
Notes: This class is very low level. If you have written some high level code based on the class, I may add it directly to the plugin to make it easier.
AESMBS.Decrypt(idata as memoryblock, odata as memoryblock=nil, iOffset as integer=0, oOffset as integer=0)
method, Encryption and Hash, MBS REALbasic Util Plugin (E4), class AESMBS, Console safe, Plugin version: 9.4, Mac OS X: Works, Windows: Works, Linux x86: Works, Feedback.

Function: Decryptes the first 16 bytes in the input memoryblock at the given offset and stores the result in the output memoryblock at the given offset.
Notes: If odata is nil, idata is used for output.
AESMBS.DecryptCBC(idata as memoryblock, LengthBytes as integer, IVector as memoryblock=nil, odata as memoryblock=nil, iOffset as integer=0, oOffset as integer=0)
method, Encryption and Hash, MBS REALbasic Util Plugin (E4), class AESMBS, Console safe, Plugin version: 9.4, Mac OS X: Works, Windows: Works, Linux x86: Works, Feedback.

Function: Decryptes the 16 byte data blocks within LengthBytes bytes in the data.
Notes:
If odata is nil, idata is used for output.
If IVector is nil, a vector filled with zeros is used.
AESMBS.DecryptCFB(idata as memoryblock, LengthBytes as integer, byref IVectorOffset as integer, IVector as memoryblock=nil, odata as memoryblock=nil, iOffset as integer=0, oOffset as integer=0)
method, Encryption and Hash, MBS REALbasic Util Plugin (E4), class AESMBS, Console safe, Plugin version: 9.5, Mac OS X: Works, Windows: Works, Linux x86: Works, Feedback.

Function: Decryptes the data in CFB128 mode.
Notes:
If odata is nil, idata is used for output.
If IVector is nil, a vector filled with zeros is used.
IVectorOffset safes the position in the IVector for the next call to this method.

The old code until plugin version 9.4 had a bug in the CFB method. This was fixed for 9.5. But the old behavior is still accessible using the methods with the Old suffix.

AESMBS.DecryptString(idata as string, IVector as memoryblock=nil) as string
method, Encryption and Hash, MBS REALbasic Util Plugin (E4), class AESMBS, Console safe, Plugin version: 9.5, Mac OS X: Works, Windows: Works, Linux x86: Works, Feedback.

Function: Decrypts a string in CFB128 mode.
Example: 
dim x,u,s as string
dim iv as MemoryBlock

s="Hello World"

// encrypt
s=ConvertEncoding(s,encodings.UTF8)

dim a as new AESMBS

call a.SetKey("1234567890123456")

iv=NewMemoryBlock(16)
x=a.EncryptString(s,iv)

MsgBox x

// decrypt

iv=NewMemoryBlock(16)
u=a.DecryptString(x,iv)

u=DefineEncoding(u,encodings.UTF8)

MsgBox u
Notes:
If IVector is nil, a vector filled with zeros is used.
The bytes from the string are read without checking the text encoding and the result string has no text encoding assigned.
