Be aware that the sequence of characters will be different and unique (is random characters generated by the process described above).

ipob_jsmith.pub - Public Key

Example for IPO (using country or organization two-letter code according to WIPO ST.3):

ipob_cr.key - Private Key
ipob_cr.pub - Public Key

Email your public key to your support contact copying the ipas mailbox (ipas@wipo.int).
