UNSUPPORTED_ALGORITHM Error
I got PlatformException (PlatformException(UNSUPPORTED_ALGORITHM, cryptography_flutter does not support algorithm null in Android., null, null))
Source code
final pbkdf2 = FlutterPbkdf2(
macAlgorithm: Hmac.sha1(),
iterations: 1001,
bits: 256,
);
final newSecretKey = await pbkdf2.deriveKeyFromPassword(password: pass, nonce: salt.codeUnits); // <-- throws error when running the deriveKeyFromPassword function.
_internal.dart
await _methodChannel.invokeMethod('encrypt', {}); <-- the error comes from this invokeMethod
It throws error only if I checked All Exception on vsCode breakpoints.

I am using AES CBC.
I already edited the CryptographyFlutterPlugin.kt file
private fun androidCipherAlgo(dartAlgo: String?): String? {
return when (dartAlgo) {
"AES_GCM" -> "AES/GCM/NoPadding"
"AES_CBC" -> "AES/CBC/NoPadding"
"CHACHA20_POLY1305_AEAD" -> "ChaCha20/Poly1305/NoPadding"
else -> null
}
}
private fun cipherMacLength(dartMacAlgo: String?): Int? {
return when (dartMacAlgo) {
"AES_GCM" -> 16
"AES_CBC" -> 32
"CHACHA20_POLY1305_AEAD" -> 16
else -> null
}
}
and still got the same error :/
Did you get this working? I have the same error on Hmac.sha512() and Hmac.sha256()
