Hi all,
I have a xml message that has the symmetric key encrypted with a public key of
the server, the xml is like
<xenc:CipherData>
<xenc:CipherValue>gIXImWs5Es6mlErowIU/TLWmqqSCsVT+quyRb1ULza1033A7SFT+4RVXG00D5463QyrnGFN3zQhv
PgAhbODOCiwm8MXyiiRQmB2Eg3uW1vWf7DevANQ8XAXw2rW4EkDLYzRpyR+kUOnJ5XGqpGjwCE8D
zTlCMswnYufhD4p7tVk=
</xenc:CipherValue>
I took the value between <xenc:CipherValue>...</xenc:CipherValue> and stored in
in the file. I later modified the file to contain 64 chars per line and then
ran below commands
1) openssl enc -base64 -d -in <file name> -out <decoded file name>
<decode file name> was created and it had binary contents. Now I went step
further
2) openssl rsautl -decrypt -inkey <privkey.pem> -out <output symmetric key file
name> -pkcs
I was expecting step 2 to work but instead go the error
RSA operation error
4696:error:0407106B:rsa routines:RSA_padding_check_PKCS1_type_2:block type is no
t 02:.\crypto\rsa\rsa_pk1.c:190:
4696:error:04065072:rsa routines:RSA_EAY_PRIVATE_DECRYPT:padding check failed:.\
crypto\rsa\rsa_eay.c:596:
Can any give pointers as to what I could be doing wrong?.
