AES Encryption Output Hex vb.net -

i figured pretty straight forward have issue getting aes encryption function return hex string. can work when convert base64 cannot string hex values. here code. appreciated.

dim aes_encryption new system.security.cryptography.rijndaelmanaged dim code_aes new system.security.cryptography.md5cryptoserviceprovider dim encrypted string = "" try     dim hash(31) byte     dim temp byte() = code_aes.computehash(system.text.asciiencoding.ascii.getbytes(pass))     array.copy(temp, 0, hash, 0, 16)     array.copy(temp, 0, hash, 15, 16)     aes_encryption.key = hash     aes_encryption.mode = ciphermode.ecb     dim aes_encryptor system.security.cryptography.icryptotransform = aes_encryption.createencryptor     dim buffer byte() = system.text.asciiencoding.ascii.getbytes(input)     encrypted = (conversion.hex(aes_encryptor.transformfinalblock(buffer, 0, buffer.length))) catch ex exception end try  return encrypted 

i've tried example, , i've got nothing either.

so tried instead of having encrypted = (conversion.hex(aes_encryptor.transformfinalblock(buffer, 0, buffer.length))), have used loop convert each byte hex equivalent, , concatenate encrypted.

dim encrypted_byte() byte = aes_encryptor.transformfinalblock(buffer, 0, buffer.length) integer = 0 encrypted_byte.length - 1     encrypted = encrypted & hex(encrypted_byte(i)).toupper next 

i'm not sure how formatted hex string in java, should @ least start.
