## Description ## Functions ### xmlSecOpenSSLEvpKeyDataAdoptEvp ()
    int
    xmlSecOpenSSLEvpKeyDataAdoptEvp (xmlSecKeyDataPtr data,
                                     EVP_PKEY *pKey);
Sets the value of key data. #### Parameters
data | the pointer to OpenSSL EVP key data. |
pKey | the pointer to EVP key. |
#### Returns 0 on success or a negative value otherwise. ### xmlSecOpenSSLEvpKeyDataGetEvp ()
    EVP_PKEY *
    xmlSecOpenSSLEvpKeyDataGetEvp (xmlSecKeyDataPtr data);
Gets the EVP_PKEY from the key data. #### Parameters
data | the pointer to OpenSSL EVP data. |
#### Returns pointer to EVP_PKEY or NULL if an error occurs. ### xmlSecOpenSSLEvpKeyDup ()
    EVP_PKEY *
    xmlSecOpenSSLEvpKeyDup (EVP_PKEY *pKey);
Duplicates `pKey` . #### Parameters
pKey | the pointer to EVP_PKEY. |
#### Returns pointer to newly created EVP_PKEY object or NULL if an error occurs. ### xmlSecOpenSSLEvpKeyAdopt ()
    xmlSecKeyDataPtr
    xmlSecOpenSSLEvpKeyAdopt (EVP_PKEY *pKey);
Creates xmlsec key object from OpenSSL key object. #### Parameters
pKey | the pointer to EVP_PKEY. |
#### Returns pointer to newly created xmlsec key or NULL if an error occurs. ## Types and Values
