Different types of encryption methods.
Symmetric encryption: This type of encryption uses the same key for both encryption and decryption. Examples of symmetric encryption algorithms include AES and Blowfish.
Asymmetric encryption: This type of encryption uses a pair of keys, one for encryption and one for decryption. Examples of asymmetric encryption algorithms include RSA and elliptic curve cryptography (ECC).
Hash functions: A hash function is a one-way encryption method that takes an input (or 'message') and produces a fixed-size string of characters, which is typically a 'digest' that can be used for data integrity and authentication. Examples of hash functions include SHA-256 and MD5.
Steganography: Steganography is the practice of hiding a secret message within an ordinary message and the extraction of it at its destination.

Are any of them unbreakable by modern technology?
It is important to note that no encryption method is completely unbreakable. The security of an encryption algorithm relies on the secrecy of the key used. As technology advances, it may become possible to break encryption methods that were once considered secure. Additionally, security weaknesses may be discovered in an encryption algorithm, making it vulnerable to attack. Therefore, it is important to use encryption methods that have been thoroughly tested and have withstood the test of time, and to use an encryption key of sufficient length.
It is also important to use a combination of different encryption methods for better security.
