Hi all,

I've been using the axutil base64 libraries recently and came across a issue in the base64.c source file (located in .../util/src/base64.c), in the following function which is used by the axutil base64 binary library to calculate the number of encoded bytes:

AXIS2_EXTERN int AXIS2_CALL axutil_base64_decode_len(const char *bufcoded) { int nbytesdecoded; register const unsigned char *bufin; register int nprbytes;

bufin = (const unsigned char *) bufcoded; while (pr2six[*(bufin++)] <= 63);

nprbytes = (bufin - (const unsigned char *) bufcoded) - 1;

nbytesdecoded = ((nprbytes + 3) / 4) * 3;

return nbytesdecoded + 1; }

I believe that this calculation of the number of encoded bytes is incorrect and have applied a quick fix as follows:

AXIS2_EXTERN int AXIS2_CALL axutil_base64_decode_len(const char *bufcoded) { int nbytesdecoded; register const unsigned char *bufin; register int nprbytes;

bufin = (const unsigned char *) bufcoded; while (pr2six[*(bufin++)] <= 63);

nprbytes = (bufin - (const unsigned char *) bufcoded) - 1;

nbytesdecoded = ((nprbytes >> 2) * 3);

if (nprbytes & 0x03) nbytesdecoded += (nprbytes & 0x03) - 1;

return nbytesdecoded; }

I hope this is of some help.

Best regards,

Royston
