| int pkcs11_decrypt | ( | pkcs11_context * | ctx, |
| int | mode, | ||
| size_t * | olen, | ||
| const unsigned char * | input, | ||
| unsigned char * | output, | ||
| size_t | output_max_len | ||
| ) |
Do an RSA private key decrypt, then remove the message padding.
- Parameters:
-
ctx PKCS #11 context mode must be RSA_PRIVATE, for compatibility with rsa.c's signature input buffer holding the encrypted data output buffer that will hold the plaintext olen will contain the plaintext length output_max_len maximum length of the output buffer
- Returns:
- 0 if successful, or an POLARSSL_ERR_RSA_XXX error code
- Note:
- The output buffer must be as large as the size of ctx->N (eg. 128 bytes if RSA-1024 is used) otherwise an error is thrown.
| void pkcs11_priv_key_free | ( | pkcs11_context * | priv_key ) |
| int pkcs11_priv_key_init | ( | pkcs11_context * | priv_key, |
| pkcs11h_certificate_t | pkcs11_cert | ||
| ) |
Initialise a pkcs11_context, storing the given certificate.
Note that the pkcs11_context will take over control of the certificate, freeing it when done.
- Parameters:
-
priv_key Private key structure to fill. pkcs11_cert PKCS #11 helper certificate
- Returns:
- 0 on success
| int pkcs11_sign | ( | pkcs11_context * | ctx, |
| int | mode, | ||
| md_type_t | md_alg, | ||
| unsigned int | hashlen, | ||
| const unsigned char * | hash, | ||
| unsigned char * | sig | ||
| ) |
Do a private RSA to sign a message digest.
- Parameters:
-
ctx PKCS #11 context mode must be RSA_PRIVATE, for compatibility with rsa.c's signature md_alg a POLARSSL_MD_* (use POLARSSL_MD_NONE for signing raw data) hashlen message digest length (for POLARSSL_MD_NONE only) hash buffer holding the message digest sig buffer that will hold the ciphertext
- Returns:
- 0 if the signing operation was successful, or an POLARSSL_ERR_RSA_XXX error code
- Note:
- The "sig" buffer must be as large as the size of ctx->N (eg. 128 bytes if RSA-1024 is used).
