Mahir Ozturk 1:efe9cad8942f 38 // Cryptography
Mahir Ozturk 1:efe9cad8942f 39 xor=>The application makes use of 'xor'. Check that it is not being used for obfuscation purposes as this can be trivially reversed.
Mahir Ozturk 1:efe9cad8942f 40 "SHA-1"=>[3]The code appears to use the SHA-1 algorithm. This is no longer considered secure and a safe alternative should be used instead.
Mahir Ozturk 1:efe9cad8942f 41 "DES"=>[3]The code appears to use the DES algorithm. This is no longer considered secure and a safe alternative such as AES should be used instead.
Mahir Ozturk 1:efe9cad8942f 42 "MD5"=>[3]The code appears to use the MD5 algorithm. This is no longer considered secure and a safe alternative should be used instead, such as SHA-2.
Mahir Ozturk 1:efe9cad8942f 43 Cipher.newInstance("DES=>[3]The code appears to use the DES algorithm. This is no longer considered secure and a safe alternative such as AES should be used instead.
Mahir Ozturk 1:efe9cad8942f 44 Cipher.newInstance("ECB=>[3]The code appears to use ECB. This is not always secure and resident properties of the plaintext may be visible in the ciphertext. An attacker may be able to analyze patterns in order to deduce properties that the encryption is intended to hide.
