CRC calculation

Hello ROOTers! I wanted to ask whether a CRC calculation class is provided inside ROOT. If not, does anyone have in mind a fast, free implemenation for 16 and 32 bit CRC calculation? Thank you in advance,

Filimon

see class TMD5

Thank you, MD5 is much safer but I really need CRC-16 and 32 to compare against some data written from detector FEE. So if anyone has already used and can suggest a free, fast CRC-32 and CRC-16 implementation I would be grateful. Thanks again,

Filimon
