I noticed that openssl(1) says that various things have been superseded by
genpkey, so I tried changing my scripts to use it. It works fine for RSA, but
the man page is not very helpful on EC. I tried
openssl genpkey -out key.new -algorithm EC -pkeyopt
ec_paramgen_curve:secp384r1
and got
parameter setting error
139638314907280:error:06089094:digital envelope
routines:EVP_PKEY_CTX_ctrl:invalid operation:pmeth_lib.c:404:
The curve works with ecparam and also shows up here:
openssl ecparam -list_curves
secp112r1 : SECG/WTLS curve over a 112 bit prime field
secp112r2 : SECG curve over a 112 bit prime field

wap-wsg-idm-ecid-wtls6: SECG/WTLS curve over a 112 bit prime field
wap-wsg-idm-ecid-wtls7: SECG/WTLS curve over a 160 bit prime field
wap-wsg-idm-ecid-wtls8: WTLS curve over a 112 bit prime field
wap-wsg-idm-ecid-wtls9: WTLS curve over a 160 bit prime field
wap-wsg-idm-ecid-wtls12: WTLS curvs over a 224 bit prime field
Any ideas on what I am doing wrong?
