[PHP] mcrypt
Hello, I am getting some odd errors trying to get an encrypt/decrypt process to work. Looking at the manual examples and some other literature, I have tried the two approaches listed below. For each, I get a sometimes-works, sometimes fails result. The manual entry has a string of user notes with problem like mine, but I still have problems. Server API Apache mcrypt mcrypt support enabled version 2.4.x Supported ciphers twofish rijndael-128 rijndael-192 rijndael-256 saferplus rc2 xtea serpent safer-sk64 safer-sk128 cast-256 loki97 gost threeway cast-128 des tripledes enigma arcfour panama wake Supported modes ofb cfb nofb cbc ecb stream --] The first attempt used the following code: --> input:$inputencrypted:$encrypted_datadecrypted:$decrypted_da ta"; ?> --] This resulted, at first, in "key: this is a secret key input:Let us meet at 9 o'clock at the secret place. encrypted:\ºþêTÏ' áz(v¹FýaõFËU³æç SäÇÚÖz ßù5Qì<±_T-:Í decrypted:Let us meet at 9 o'clock at the secret place." BUT after I refreshed/reloaded a couple of times, I got this: "Warning: mcrypt_generic_init: Memory allocation error in /home/pndrdrm001/www/administrator/crypt.php on line 64 Warning: 1 is not a valid MCrypt resource in /home/pndrdrm001/www/administrator/crypt.php on line 65 Warning: 1 is not a valid MCrypt resource in /home/pndrdrm001/www/administrator/crypt.php on line 66 Warning: 1 is not a valid MCrypt resource in /home/pndrdrm001/www/administrator/crypt.php on line 67 key: this is a secret key input:Let us meet at 9 o'clock at the secret place. encrypted: decrypted: " There were no changes to the code.

Is there a missing call to free resources, or something? What can be done? Thanks! Regards, Puru

Re: [PHP] synchronize functions
something similar to the synchronization of functions in java. Onle one thread should be able to access that method. I guess you can use semaphores. Even I am trying to find out how to do it in any other fashion.

[PHP] Application level logging module
Hi all, Did anyone work on application level logging module ? Please let me know the correct architecture, since I am not able to create a singleton per webserver. Thanks Regards, Puru
[PHP] singleton feature
Hi , I have a small suggestion. I guess it is a good feature to have a provision to have a Singleton class per webserver instance. This is especially useful for maintain user defined connection pools, loggers etc. Thanks Regards, Puru
[PHP] Re: [PHP-DEV] singleton feature
Singleton means only one instance.. i.e. instance of a class per webserver... all application scripts should talk only to that same instance irrespective of the request. p - Original Message - From: "Alexander Skwar" <[EMAIL PROTECTED]> To: "Purushotham Komaravolu" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Monday, June 24, 2002 2:53 PM Subject: Re: [PHP-DEV] singleton feature So sprach Purushotham Komaravolu am 2002-06-24 um 11:39:36 -0700 : > > Hi , > I have a small suggestion.
