问题 I encrypted a string in ColdFusion using: <cfset strEnc=ToBase64(Encrypt("some text","123", "AES","Base64"))> I can decrypt the string in ColdFusion using: <cfset strDec=ToString(Decrypt(ToBinary(strEnc), "123", "AES","Base64"))> But I am unable to decrypt strEnc in PHP. I have found some decrypt functions in PHP. But they require an iv parameter. Can anyone help me? 回答1: The native methods offered by each language will vary in terms of expected arguments, parameters and encryptions methods.

问题 I try to make encryption and decryption mechanism in Java. I have found some code for decrypting but I don't know how to encrypt. What encryption method will be compatible with decryption method like this: private byte[] padKey(byte[] key) { byte[] paddedKey = new byte[32]; System.arraycopy(key, 0, paddedKey, 0, key.length); return paddedKey; } private byte[] unpad(byte[] data) { byte[] unpaddedData = new byte[data.length - data[data.length - 1]]; System.arraycopy(data, 0, unpaddedData, 0,

问题 I wish to run a C program(works fine using gcc) on android. I have installed ndk for eclipse and have setup the basic things correctly. I have linked openssl library(.so files) to the project. Methods such as AES_set_encrypt_key aren't facing any issue but I am getting error at AES_KEY/AES_BLOCK_SIZE saying type/symbol cannot be resolved . How to fix this? Thanks 回答1: I found the solution. There was a problem with the extern statements in aes.h header file in eclipse IDE. As I was using it in

问题 I am implementing compatible binary file encryption/decryption between .NET and Objective-C apps . I am using RNCryptor package on Objective-C side. As far as I reached, I am able to encrypt/decrypt strings, but file encryption is troubling me. The problem is, when I read file and encrypt its data and write it to a file, it doesn't decrypt in .NET app . If I calculate Base64 string of encrpted data and decrypt that in .NET - creating byte array from Base64 string and decrypt with same login

问题 I am trying to do AES Encryption in my windows phone8 app. I searched a lot, but couldn't get a clear view to do so. Can anybody give me link that gives the clear example of implementing AES Encryption ni WP8 App. What i need to do is, 1)I need to pass key, initial vector, and value as strings. 2)need to encrypt that string in any format of AES Encryption, and finally need to get the encrypted value as string. Can anybody help me. am using this example and using UTF8 encoding for key, and Iv

问题 I have written a process where a file is encrypted and uploaded to Azure, then the download process has to be decrypted which is what fails with a "Padding is invalid and cannot be removed" error, or a "Length of the data to decrypt is invalid." error. I've tried numerous solutions online, including C# Decrypting mp3 file using RijndaelManaged and CryptoStream, but none of them seem to work and I end up just bouncing back and forth between these two errors. The encryption process uses the

问题 I want to decrypt AES 128 in Universal app (win 10), but we do not have AesManaged because this lib doesn't exist in System.Security.Cryptography. So, how can I decrypt my string in UWA c#? I use this code in windows phone 8 : public static string DecryptString(string cipherText) { const string password = "myPass"; string plaintext = null; try { if (!string.IsNullOrEmpty(cipherText)) { if (cipherText != "") { var key = new byte[KeySize]; var passwordbytes = Encoding.UTF8.GetBytes(password);

问题 I have a string that comes from an AES encryption like this -> "‚±«~—ÄÔý 3ƒÛœÛ" Is there a way to encode this string so it can be transmitted to a script via URL? Thank You! 回答1: you can use urlencode or base64_encode for that task, both will produce url safe strings 回答2: Yes! Use the global function urlencode($string) If you want to get the original paramters you can decode the URL-Parameters with: urldecode($string) 来源： https://stackoverflow.com/questions/15011680/is-there-a-way-in-php-to

问题 I am currently having an issue of not being able to decrypt the text provided after encryption. It returns: Key: ﾝƚ!*!ﾞﾫø}Qd`Dﾫd!Þxͦ}ﾰﾐﾡ>'U Unpadded Text: Hello World Padded Text: Hello World Salt: h5eE0b814M Encrypted Text: WxCž~¼!Ò]Cú´=P+ Encrypted Text with Salt: h5eE0b814MWxCž~¼!Ò]Cú´=P+ Key: ﾝƚ!*!ﾞﾫø}Qd`Dﾫd!Þxͦ}ﾰﾐﾡ>'U Unencrypted Text: Where Unencrypted Text: Should be "Unencypted Text: Hello World" Two programs are used in this, one a module and a master.

问题 We have a column of type varchar(25) in a SQL Server table that mistakenly had plain text values inserted when they should have been encrypted with AES. We are going to remove the plain text values from the database. The plan was to verify the block size of the field, though this would cause some unencrypted values to be left. Is there any other criteria I can check to reliably identify valid encrypted data? We need it to be a T-SQL only solution. Update Just dug a little deeper, it's getting
