Hi all,

The RDE deposit spec is located here: https://www.icann.org/en/system/files/files/rde-specs-09nov07-en.pdf

Escrow records shall be compiled into a single (uncompressed) CSV text file or multiple (uncompressed) text files approximately 1 gigabyte or one million rows in size, in compliance with RFC 4180 . In accordance with RFC 4180, the character encoding for the CSV file should be US-ASCII, although UTF-8 is also permissible.
https://tools.ietf.org/html/rfc4180

I do not see the EPP code/auth code mentioned as a requirement so that makes things more complex, at least more complex then EPP I assume. 

Best regards,

Theo Geurts
