OldAESMBS.Decrypt(idata as memoryblock, odata as memoryblock=nil, iOffset as Integer=0, oOffset as Integer=0)
Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 9.4 ✅ Yes ✅ Yes ✅ Yes ❌ No Desktop, Console & Web
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.
This is ECB mode.
OldAESMBS.DecryptCBC(idata as memoryblock, LengthBytes as Integer, IVector as memoryblock=nil, odata as memoryblock=nil, iOffset as Integer=0, oOffset as Integer=0)
Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 9.4 ✅ Yes ✅ Yes ✅ Yes ❌ No Desktop, Console & Web
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.
OldAESMBS.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)
Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 9.5 ✅ Yes ✅ Yes ✅ Yes ❌ No Desktop, Console & Web
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.
iOffset: offset in idata.
oOffset: offset in odata.
LengthBytes: Length of data in idata and odata.

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.

OldAESMBS.DecryptString(idata as string, IVector as memoryblock=nil) as string
Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 9.5 ✅ Yes ✅ Yes ✅ Yes ❌ No Desktop, Console & Web
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 OldAESMBS

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.
