This will work with several shells and won't with others. Some shells (honestly, i don't know if bash is among them) have limits on the maximum numbers of elements an array can hold: ksh88 for instance 1023, ksh93 more than that, even if i can't remember how many.
It is usually best to stay as far away as possible from the limits, so i wouldn't use arrays for any data which could even come into the vicinity of 1000, but arguably my scripting style is far too defensive to be optimal. Having had to administrate abour 20k servers worldwide once did that for me: every conceivable nightmare was sure to be encountered on at least half a dozen systems and one gets to take absolutely nothing for granted.
How about this, using shell methods:
I hope this helps.

ERR_error_string(3) OpenSSL ERR_error_string(3)NAME
ERR_error_string, ERR_error_string_n, ERR_lib_error_string, ERR_func_error_string, ERR_reason_error_string - obtain human-readable error
message
SYNOPSIS
#include <openssl/err.h>
char *ERR_error_string(unsigned long e, char *buf);
char *ERR_error_string_n(unsigned long e, char *buf, size_t len);
const char *ERR_lib_error_string(unsigned long e);
const char *ERR_func_error_string(unsigned long e);
const char *ERR_reason_error_string(unsigned long e);
DESCRIPTION
ERR_error_string() generates a human-readable string representing the error code e, and places it at buf. buf must be at least 120 bytes
long. If buf is NULL, the error string is placed in a static buffer. ERR_error_string_n() is a variant of ERR_error_string() that writes
at most len characters (including the terminating 0) and truncates the string if necessary. For ERR_error_string_n(), buf may not be NULL.
The string will have the following format:
error:[error code]:[library name]:[function name]:[reason string]
error code is an 8 digit hexadecimal number, library name, function name and reason string are ASCII text.
ERR_lib_error_string(), ERR_func_error_string() and ERR_reason_error_string() return the library name, function name and reason string
respectively.
The OpenSSL error strings should be loaded by calling ERR_load_crypto_strings(3) or, for SSL applications, SSL_load_error_strings(3) first.
If there is no text string registered for the given error code, the error string will contain the numeric code.
ERR_print_errors(3) can be used to print all error codes currently in the queue.
RETURN VALUES
ERR_error_string() returns a pointer to a static buffer containing the string if buf == NULL, buf otherwise.
ERR_lib_error_string(), ERR_func_error_string() and ERR_reason_error_string() return the strings, and NULL if none is registered for the
error code.
SEE ALSO err(3), ERR_get_error(3), ERR_load_crypto_strings(3), SSL_load_error_strings(3)ERR_print_errors(3)HISTORY
ERR_error_string() is available in all versions of SSLeay and OpenSSL. ERR_error_string_n() was added in OpenSSL 0.9.6.
