Codificar una cadena de texto en MD5 con PHP es muy sencillo gracias a las funci\u00f3n md5()<\/strong>. Veamos un ejemplo:<\/p>\n

[PHP]<\/p>\n

$cadena = \u00abTexto a encriptar\u00bb;
\n$cadena_encript = md5($cadena);<\/p>\n

[\/PHP]<\/p>\n

O simplemente:<\/p>\n

[PHP]
\n$cadena_encript = md5(\u00abTexto a encriptar\u00bb);<\/p>\n

[\/PHP]<\/p>\n

Esta funci\u00f3n es muy utilizada para guardar contrase\u00f1as encriptadas en base de datos. De esta manera aumentamos mucho la seguridad ya que el algoritmo MD5 es de una sola direcci\u00f3n, no pudi\u00e9ndose desencriptar.<\/p>\n","protected":false},"excerpt":{"rendered":"
