I am trying to generate RSA keypair using openssl library and then read the same keys later. However, it fails. Sometimes it gives me this error: error:0906D06C:PEM routines:

openssl documentation: Generate RSA Key. Example. In order to generate an RSA key, an EVP_PKEY must first be allocated with EVP_PKEY_new:. EVP_PKEY *pkey; pkey = EVP_PKEY_new(); RSA_verify. Now that we have signed our content, we want to verify its signature. The method for this action is (of course) RSA_verify().The inputs to the action are the content itself as a buffer buf of bytes or size buf_len, the signature block sig of size sig_len as generated by RSA_sign(), and the X509 certificate corresponding to the private key used for the signature. The function EVP_PKEY_encrypt() can be called more than once on the same context if several operations are performed using the same parameters. Return Values. EVP_PKEY_encrypt_init() and EVP_PKEY_encrypt() return 1 for success and 0 or a negative value for failure. In particular a return value of -2 indicates the operation is not supported by 14 #include 15 #include 16 #include 17 #include 18 #include 19 #include May 29, 2020 · Consider OpenSSL contexts, which are created by EVP_CIPHER_CTX_new and must be initialized with algorithm, key, etc. before actual use.

The EVP digest routines are a high level interface to message digests.. EVP_MD_CTX_init() initializes digest context ctx. EVP_MD_CTX_create() allocates, initializes and returns a digest context. EVP_DigestInit_ex() sets up digest context ctx to use a digest type from ENGINE impl.ctx must be initialized before calling this function.type will typically be supplied by a function such as EVP_sha1().

The EVP_MD_CTX_cleanup() function was merged into EVP_MD_CTX_reset() which is called by EVP_MD_CTX_free(). Adjust the documentation to say that the latter should be used to avoid leaking memory. CLA: trivial Reviewed-by: Andy Polyakov Reviewed-by: Rich Salz (Merged from #5921)
