SSL_get_psk_identity(3SSL) OpenSSL SSL_get_psk_identity(3SSL)NAME
SSL_get_psk_identity, SSL_get_psk_identity_hint - get PSK client identity and hint
SYNOPSIS
#include <openssl/ssl.h>
const char *SSL_get_psk_identity_hint(const SSL *ssl);
const char *SSL_get_psk_identity(const SSL *ssl);
DESCRIPTION
SSL_get_psk_identity_hint() is used to retrieve the PSK identity hint used during the connection setup related to SSL object ssl.
Similarly, SSL_get_psk_identity() is used to retrieve the PSK identity used during the connection setup.
RETURN VALUES
If non-NULL, SSL_get_psk_identity_hint() returns the PSK identity hint and SSL_get_psk_identity() returns the PSK identity. Both are
NULL-terminated. SSL_get_psk_identity_hint() may return NULL if no PSK identity hint was used during the connection setup.
Note that the return value is valid only during the lifetime of the SSL object ssl.

SSL_CTX_use_psk_identity_hint(3SSL) OpenSSL SSL_CTX_use_psk_identity_hint(3SSL)NAME
SSL_CTX_use_psk_identity_hint, SSL_use_psk_identity_hint, SSL_CTX_set_psk_server_callback, SSL_set_psk_server_callback - set PSK identity
hint to use
SYNOPSIS
#include <openssl/ssl.h>
int SSL_CTX_use_psk_identity_hint(SSL_CTX *ctx, const char *hint);
int SSL_use_psk_identity_hint(SSL *ssl, const char *hint);
void SSL_CTX_set_psk_server_callback(SSL_CTX *ctx,
unsigned int (*callback)(SSL *ssl, const char *identity,
unsigned char *psk, int max_psk_len));
void SSL_set_psk_server_callback(SSL *ssl,
unsigned int (*callback)(SSL *ssl, const char *identity,
unsigned char *psk, int max_psk_len));
DESCRIPTION
SSL_CTX_use_psk_identity_hint() sets the given NULL-terminated PSK identity hint hint to SSL context object ctx.
SSL_use_psk_identity_hint() sets the given NULL-terminated PSK identity hint hint to SSL connection object ssl. If hint is NULL the current
hint from ctx or ssl is deleted.
In the case where PSK identity hint is NULL, the server does not send the ServerKeyExchange message to the client.
A server application must provide a callback function which is called when the server receives the ClientKeyExchange message from the
client. The purpose of the callback function is to validate the received PSK identity and to fetch the pre-shared key used during the
connection setup phase. The callback is set using functions SSL_CTX_set_psk_server_callback() or SSL_set_psk_server_callback(). The
callback function is given the connection in parameter ssl, NULL-terminated PSK identity sent by the client in parameter identity, and a
buffer psk of length max_psk_len bytes where the pre-shared key is to be stored.
RETURN VALUES
SSL_CTX_use_psk_identity_hint() and SSL_use_psk_identity_hint() return 1 on success, 0 otherwise.
Return values from the server callback are interpreted as follows:
> 0 PSK identity was found and the server callback has provided the PSK successfully in parameter psk. Return value is the length of psk in
bytes. It is an error to return a value greater than max_psk_len.
If the PSK identity was not found but the callback instructs the protocol to continue anyway, the callback must provide some random
data to psk and return the length of the random data, so the connection will fail with decryption_error before it will be finished
completely.
0 PSK identity was not found. An "unknown_psk_identity" alert message will be sent and the connection setup fails.

I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
