Implementing file transfer assurance using Checksum of files in coldfusion

[Abdul L Koyappayil]

I want to do file transfer (SFTP). Since there are lots of files I want to implement a file transfer completeness assurance system in coldfusion using any Checksum techniques so as to make sure file has been completely transferred to destination and it is same as the source file. Is there any way to achieve this in Coldfusion ?. Or is there any way to do this in coldfusion with the help of any libraries?.

Hi, Abdul,

Ben Nadel has a couple of blog entries that might help.

Thanks for your response. But we cannot do this (crc and adler) for file right??

I've been giving it some more thought, and realized that you were not looking for an upload solution, you are looking for an SFTP solution.  But CF does have the ability to generate a checksum.
