decrypt

@Nullable static fun decrypt(cipherText: Bytes!, key: Key!, nonce: Nonce!): Bytes? (source)

Decrypt a message using a key.

Parameters

cipherText - Bytes!: The cipher text to decrypt.

key - Key!: The key to use for decryption.

nonce - Nonce!: The nonce that was used for encryption.

Return
Bytes?: The decrypted data, or null if verification failed.

@Nullable static fun decrypt(cipherText: Allocated!, key: Key!, nonce: Nonce!): Allocated? (source)

Decrypt a message using a key.

Parameters

cipherText - Allocated!: The cipher text to decrypt.

key - Key!: The key to use for decryption.

nonce - Nonce!: The nonce that was used for encryption.

Return
Allocated?: The decrypted data, or null if verification failed.

@Nullable static fun decrypt(cipherText: ByteArray!, key: Key!, nonce: Nonce!): ByteArray? (source)

Decrypt a message using a key.

Parameters

cipherText - ByteArray!: The cipher text to decrypt.

key - Key!: The key to use for decryption.

nonce - Nonce!: The nonce that was used for encryption.

Return
ByteArray?: The decrypted data, or null if verification failed.

@Nullable static fun decrypt(cipherText: Bytes!, password: String!): Bytes? (source)

Decrypt a message using a password, 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 - Bytes!: The cipher text to decrypt.

password - String!: The password that was used for encryption.

Return
Bytes?: The decrypted data, or null if verification failed.

Parameters

cipherText - ByteArray!: The cipher text to decrypt.

password - String!: The password that was used for encryption.

Return
ByteArray?: The decrypted data, or null if verification failed.

@Nullable static fun decrypt(cipherText: Bytes!, password: String!, algorithm: Algorithm!): Bytes? (source)
