NAME
       errstr - lookup error codes

SYNOPSIS
       openssl errstr error_code

DESCRIPTION
       Sometimes an application will not load error message and only numerical forms will be available. The errstr utility can be used to display
       the meaning of the hex code. The hex code is the hex digits after the second colon.

EXAMPLE
       The error code:

	27594:error:2006D080:lib(32):func(109):reason(128):bss_file.c:107:

       can be displayed with:

	openssl errstr 2006D080

       to produce the error message:

	error:2006D080:BIO routines:BIO_new_file:no such file
