It (3DES Wrapper) will encrypt them, but any attempt to decrypt a string greater than 7 characters generates the error Invalid length for a Base-64 char array. I have reproduced on several machines running 1.6.6 using very simple code to decrypt and enrypt a string (no BO's, no custom anything).

For example "1111111" encrypts and decrypts fine, but "11111111" will encrypt but not decrypt.

Any insight appreciated as always.

The occurs in tripledeswrapper.vb at the function Decrypt, in the first line of the function:

Public Function Decrypt(ByVal text As String) As String

Dim input() As Byte = Convert.FromBase64String(text)

Dim output() As Byte = Transform(input, m_des.CreateDecryptor(m_key, m_iv))

Return m_utf8.GetString(output)

End Function

yup nothing pretty about it, I have no control over it either, they have to be encrypted at the database level. Thank you for the comments and ideas, I'll let you know how it works out Smile
