Hi Arek,
Thanks for quick response.
I am using resulted output vector to verify the encrypted message.
I thought the encrypted data will be in the asym_op->rsa.message.data after
rte_cryptodev_enqueue_burst and rte_cryptodev_enqueue_burst call with operation
type RTE_CRYPTO_ASYM_OP_ENCRYPT.
So ,I checked the hex_dump of asym_op->rsa.message.data.
Code snippet:
asym_op = result_op->asym;
debug_hexdump(stdout, "encrypted message", asym_op->rsa.message.data,
asym_op->rsa.message.length);
Encrypted data will be placed in asym_op->rsa.cipher.data after crypto
operation is my understanding is correct ?
I should use
debug_hexdump(stdout, "encrypted message", asym_op->rsa.cipher.data,
asym_op->rsa.cipher.length);
to check the encrypted message for the input given?
Regards,
Bala

Hi Bala,
Ciphertext will be written into asym_op->rsa.cipher.data (not message.data) by
the PMD, here you are using same address for both hex dumps.
Although there is a bug in debug_hexdump in this function which may cause this
confusion.
Plus, the test you are referring is PWCT test (Pairwise conditional test) -> it
will encrypt, then decrypt.
Please take a look into this comment in queue_ops_rsa_enc_dec function:
/* Use the resulted output as decryption Input vector*
So above this line there is an encryption part.
Below is decryption.
Regards,
Arek

Subject: how to use crypto openssl PMD for asymmetric encryption and decryption
Hi All,
I am new to dpdk. Planning to use openssl crypto PMD for
encrypting/decrypting the packets.
Couldn't find much documents on openssl PMD for asymmetric
encryption/decryption.
Any one please point me in the right document.
I have tried to run the test cases wrote for asymmetric crypto using openssl
virtual PMD.
But the output of particular test case is same after the encryption done.
File : app/test/test_cryptodev_asym.c
Test executable: ./app/test/dpdk-test
Test case : test_rsa_enc_dec
Input given to encryption:
message at [0x1894e60], len=20
00000000: F8 BA 1A 55 D0 2F 85 AE 96 7B B6 2F B6 CD A8 EB | ...U./...{./....
00000010: 7E 78 A0 50 | ~x.P
After processing the output also looks like same :
encrypted message exist at [0x1894e60], len=20
00000000: F8 BA 1A 55 D0 2F 85 AE 96 7B B6 2F B6 CD A8 EB | ...U./...{./....
00000010: 7E 78 A0 50
Regards,
Bala
