Cannot verify openssl smime verify over SSH -

i'm trying ssh server @ university in order openssl assignment. have self-signed certificate aasignedcert.pem, private key signed aaprivatekey.pem , plaintext test.txt.

i first signed message create testsigned.txt file command:

openssl smime -sign -signer aasignedcert.pem -in test.txt -inkey aaprivatekey.pem > testsigned.txt

then, encrypted file create testsigned.txt.enc:

openssl smime -encrypt -in testsigned.txt -aes128 aasignedcert.pem > test.txt.enc

to create sure works, decrypted file , stored in testsigned.dec.txt:

openssl smime -decrypt -aes128 -in test.txt.enc -inkey aaprivatekey.pem > test.dec.txt

the decrypted file indeed has original plaintext. finally, attempted verify using certificate signed with:

openssl smime -verify -in test.dec.txt -cafile aasignedcert.pem -certfile aasignedcert.pem

this, however, not work. fiddling parameters, consistently error message:

verification failure 139814549997256:error:21075075:pkcs7 routines:pkcs7_verify:certificate verify error:pk7_smime.c:342:verify error:unable local issuer certificate

i cannot figure out i'm doing wrong. have idea?

how did create aasignedcert.pem? perhaps self-signed using local ca created? if case, believe need pass the certificate of ca -cafile argument.

openssl smime -verify -in test.dec.txt -cafile [certifcate of ca] -certfile aasignedcert.pem
