snmpv3 Decryption error with net-snmp 5.2.1

[Stage Iup - Fabrice & Frédéric]

Hi all

I use net-snmp 5.2.1, i have created a snmpv3 user with : net-snmp-config --create-snmpv3-user -ro -x mypassword -X DES -A MD5 myuser

and when I want to send this request at the agent : snmpget -v 3 -u myuser -l authPriv -a MD5 -A mypassword -x DES -X mypassword localhost sysUpTime.0
 i have the following error : snmpget: Decryption error

so if anybody have an idea on how to resolve this problem....
