Ta’rif va qo‘llanilishi
md5() funksiyasi stringning MD5 xeshini hisoblaydi.
md5() funksiyasi RSA Data Security, Inc. kompaniyasining MD5 Message-Digest algoritmidan foydalanadi.
RFC 1321 - The MD5 Message-Digest Algorithm hujjatidan: "The MD5 message-digest algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. The MD5 algorithm is intended for digital signature applications, where a large file must be "compressed" in a secure manner before being encrypted with a private (secret) key under a public-key cryptosystem such as RSA."
Faylning MD5 xeshini hisoblash uchun md5_file() funksiyasidan foydalaning.
