read simply reads standard input. You probably want to use redirection.

Code:
while read line; do
  echo "Read line '$line'"
done <file

Without concrete information about which particular string at which particular position, it's hard to do anything useful inside that loop, but it should hopefully be enough to get you started.

ssl_rstate_string

SSL_rstate_string(3SSL) 					      OpenSSL						   SSL_rstate_string(3SSL)

NAME

       SSL_rstate_string, SSL_rstate_string_long - get textual description of state of an SSL object during read operation

SYNOPSIS

	#include <openssl/ssl.h>

	const char *SSL_rstate_string(SSL *ssl);
	const char *SSL_rstate_string_long(SSL *ssl);

DESCRIPTION

       SSL_rstate_string() returns a 2 letter string indicating the current read state of the SSL object ssl.

       SSL_rstate_string_long() returns a string indicating the current read state of the SSL object ssl.

NOTES

       When performing a read operation, the SSL/TLS engine must parse the record, consisting of header and body. When working in a blocking
       environment, SSL_rstate_string[_long]() should always return "RD"/"read done".

       This function should only seldom be needed in applications.

RETURN VALUES

       SSL_rstate_string() and SSL_rstate_string_long() can return the following values:

       "RH"/"read header"
	   The header of the record is being evaluated.

       "RB"/"read body"
	   The body of the record is being evaluated.

       "RD"/"read done"
	   The record has been completely processed.

       "unknown"/"unknown"
	   The read state is unknown. This should never happen.

SEE ALSO
