decryptDetached

@Nullable static fun decryptDetached(cipherText: Bytes, mac: Bytes, key: Key, nonce: Nonce): Bytes? (source)
@Nullable static fun decryptDetached(cipherText: ByteArray, mac: ByteArray, key: Key, nonce: Nonce): ByteArray? (source)

Decrypt a message using a key and a detached message authentication code.

Parameters

cipherText - The cipher text to decrypt.

mac - The message authentication code.

key - The key to use for decryption.

nonce - The nonce that was used for encryption.

Return
The decrypted data, or null if verification failed.

@Nullable static fun decryptDetached(cipherText: Bytes, mac: Bytes, password: String): Bytes? (source)
@Nullable static fun decryptDetached(cipherText: ByteArray, mac: ByteArray, password: String): ByteArray? (source)

Decrypt a message using a password and a detached message authentication code, using PasswordHash for the key generation (with the currently recommended algorithm and limits on operations and memory that are suitable for most use-cases).

Parameters

cipherText - The cipher text to decrypt.

mac - The message authentication code.

password - The password that was used for encryption.

Return
The decrypted data, or null if verification failed.

@Nullable static fun decryptDetached(cipherText: Bytes, mac: Bytes, password: String, algorithm: Algorithm): Bytes? (source)
@Nullable static fun decryptDetached(cipherText: ByteArray, mac: ByteArray, password: String, algorithm: Algorithm): ByteArray? (source)

Decrypt a message using a password and a detached message authentication code, using PasswordHash for the key generation (with limits on operations and memory that are suitable for most use-cases).

Parameters

cipherText - The cipher text to decrypt.

mac - The message authentication code.

password - The password that was used for encryption.

algorithm - The algorithm that was used for encryption.

Return
The decrypted data, or null if verification failed.

opsLimit - The opsLimit that was used for encryption.

memLimit - The memLimit that was used for encryption.

algorithm - The algorithm that was used for encryption.

Return
The decrypted data, or null if verification failed.
