MD MessageDigest Algorithm. Calculates the SHA family of hash functions SHA SHA SHA and SHA. AESDECRYPT decrypts the encrypted string cryptstr using the key string keystr and returns the original cleartext string. For more information see the description of AESENCRYPT. However it is possible for AESDECRYPT to return a non NULL value possibly garbage if the input data or the key is invalid

Br br Advertise Partners Not found hashesEmpty strings are stored as empty strings. You must convert the value to a nonbinary string. To avoid exposing these applications can use stored procedures to encrypt and decrypt values on the server side. On systems where this function supports multiple algorithms the constants above are set to quotquot if supported and quotquot otherwise. DESDECRYPT cryptstr keystr If crypt is not available on your system as is the case with Windows ENCRYPT always returns NULL. PHP checks what algorithms are available and what algorithms to use when it is installed

The value of these constants are set by PHP when it is installed. As of MySQL the return value is a nonbinary string in the connection character set. COMPRESS stringtocompress SHA str hashlength Note There is no decrypt function. Make sure to specify a strong enough salt for better security. Before the return value is a binary string. Decrypts a string encrypted with DESENCRYPT. DESDECRYPT cryptstr keystr If crypt is not available on your system as is the case with Windows ENCRYPT always returns NULL. The oldpasswords system variable controls the password hashing method used by the PASSWORD function. Returns the length that the compressed string had before being compressed. As of MySQL the return value is a nonbinary string in the connection character set. If either argument is NULL or the hash length is not one of the permitted values the return value is NULL. Passwords or other sensitive values supplied as arguments to encryption functions are sent in cleartext to the MySQL server unless an SSL connection is used

If either argument is NULL or the hash length is not one of how to get rid of chinch bugs the permitted values the return value is NULL


To avoid these types of exposure applications can encrypt sensitive values on the client side before sending them to the server. ENCODE str passstr OLDPASSWORD str The encryption key to use is chosen based on the second argument to DESENCRYPT if one was given. For that purpose consider a more secure function such as AESENCRYPT or SHA instead. The return value is a nonbinary string in the connection character set a binary string before MySQL or NULL if the argument is NULL. Otherwise the return value is always NULL



The key file can be specified with How to play 3 dice cee lo the deskeyfile server option. One benefit of having a set of default keys is that it gives applications a way to check for the existence of encrypted column values without giving the end user the right to decrypt those values. The salt parameter is optional. Before the return value is a binary string see the notes at the beginning of this section about using the value as a nonbinary string.

    The key file can be specified with the deskeyfile server option. There should be at least one space between the number and the key. The ENCODE function should no longer be used. The first argument is the cleartext string to be hashed. As of MySQL the return value is a nonbinary string in the connection character set. See the notes at the beginning of this section about storing hash values efficiently
