This function sets the tag-designated RSA key component into the established\r
RSA context from the user-specified non-negative integer (octet string format\r
represented in RSA PKCS#1).\r
- If BigNumber is NULL, then the specified key componenet in RSA context is cleared.\r
+ If BigNumber is NULL, then the specified key component in RSA context is cleared.\r
\r
If RsaContext is NULL, then return FALSE.\r
\r
@param[in, out] RsaContext Pointer to RSA context being set.\r
@param[in] KeyTag Tag of RSA key component being set.\r
@param[in] BigNumber Pointer to octet integer buffer.\r
- If NULL, then the specified key componenet in RSA\r
+ If NULL, then the specified key component in RSA\r
context is cleared.\r
@param[in] BnSize Size of big number buffer in bytes.\r
If BigNumber is NULL, then it is ignored.\r
