***** Create a self signed cert ************
1) openssl genrsa 512 > client-key.pem
2) openssl req -new -x509 -nodes -md5 -days 1000 -key client-key.pem > client-cert.pem
3) note sha1 would be -sha1
-- adding metadata to beginning
3) openssl x509 -in client-cert.pem -text > tmp.pem
4) mv tmp.pem client-cert.pem
***** Create a CA, signing authority **********
same as self signed, use ca prefix instead of client
***** Create a cert signed by CA **************
1) openssl req -newkey rsa:512 -md5 -days 1000 -nodes -keyout server-key.pem > server-req.pem
* note if using exisitng key do: -new -key keyName
2) copy ca-key.pem (why ????)
3) openssl x509 -req -in server-req.pem -days 1000 -md5 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > server-cert.pem
***** To create a dsa cert ********************
1) openssl dsaparam 512 > dsa512.param # creates group params
2) openssl gendsa dsa512.param > dsa512.pem # creates private key
3) openssl req -new -x509 -nodes -days 1000 -key dsa512.pem > dsa-cert.pem
***** To convert from PEM to DER **************
a) openssl x509 -in cert.pem -inform PEM -out cert.der -outform DER
to convert rsa private PEM to DER :
b) openssl rsa -in key.pem -outform DER -out key.der
**** To encrypt rsa key already in pem **********
a) openssl rsa <server-key.pem.bak -des >server-keyEnc.pem
note location of des, pass = yassl123
*** To make a public key from a private key ******
openssl rsa -in 1024rsa.priv -pubout -out
**** To convert to pkcs8 *******
openssl pkcs8 -nocrypt -topk8 -in server-key.pem -out server-keyPkcs8.pem
**** To convert to pkcs8 encrypted *******
openssl pkcs8 -topk8 -in server-key.pem -out server-keyPkcs8Enc.pem
passwd: yassl123
to use PKCS#5 v2 instead of v1.5 which is default add
-v2 des3 # file Pkcs8Enc2
to use PKCS#12 instead use -v1 witch a 12 algo like
-v1 PBE-SHA1-RC4-128 # file Pkcs8Enc12 , see man pkcs8 for more info
**** To convert from pkcs8 to traditional ****
openssl pkcs8 -nocrypt -in server-keyPkcs8.pem -out server-key.pem
*** DH paramters ***
openssl dhparam 2048 > dh2048.param
to add metadata
openssl dhparam -in dh2048.param -text > dh2048.pem
**** ECC ******
1) make a key
to see types available do
openssl ecparam -list_curves
make a new key
openssl ecparam -genkey -text -name secp256r1 -out ecc-key.pem
*** CRL ***
1) create a crl
a) openssl ca -gencrl -crldays 120 -out crl.pem -keyfile ./ca-key.pem -cert ./ca-cert.pem
Error No ./CA root/index.txt so:
b) touch ./CA root/index.txt
a) again
Error No ./CA root/crlnumber so:
c) touch ./CA root/crlnumber
a) again
Error unable to load CRL number
d) add '01' to crlnumber file
a) again
2) view crl file
openssl crl -in crl.pem -text
3) revoke
openssl ca -revoke server-cert.pem -keyfile ./ca-key.pem -cert ./ca-cert.pem
Then regenerate crl with a)
4) verify
openssl verify -CAfile ./ca-cert.pem ./server-cert.pem
Make file with both ca and crl
cat ca-cert.pem crl.pem > ca-crl.pem
openssl verify -CAfile ./ca-crl.pem -crl_check ./ca-cert.pem
