For now, crypto API quietly used cipher witout IV if a cipher algorithm wihtou IV specificaton was used (e.g. aes-xts). This caused fail later during activation. This patch allows only two specific backed use without specified IV (ECB mode and NULL cipher). Also check cipher string early during parsing of CLI options.
