DES (Data Encryption Standard)
A symmetric key encryption algorithm that encrypts data in 64-bit blocks using a 56-bit key. It is now considered insecure due to the small key size.
Twofish
A symmetric key block cipher considered as one of the fastest encryption algorithms. It uses 128-bit blocks and supports key sizes of 128, 192, or 256 bits.
Blowfish
A symmetric encryption algorithm designed to replace DES. It encrypts data in 64-bit blocks and supports variable-length keys from 32 to 448 bits.
RSA (Rivest-Shamir-Adleman)
An asymmetric encryption algorithm that is based on the computational difficulty of factoring large integers. Key lengths typically range from 1024 to 4096 bits.
AES (Advanced Encryption Standard)
A symmetric encryption algorithm that encrypts fixed blocks of data, typically 128 bits, using symmetric keys. Key lengths can be 128, 192, or 256 bits.
3DES (Triple Data Encryption Standard)
An enhancement of the original DES that applies the DES cipher algorithm three times to each data block. Key lengths are 168, 112, or 56 bits, but it's considered to be 112 bits secure due to meet-in-the-middle attack.
Quantum Cryptography
Based on the principles of quantum mechanics. Quantum Key Distribution (QKD) uses quantum properties to exchange cryptographic keys securely. No fixed key length, as it is unaffected by computational power.
Diffie-Hellman
A method of securely exchanging cryptographic keys over a public channel. Not an encryption algorithm itself, but key lengths are generally the same as RSA for comparable security.
ECC (Elliptic Curve Cryptography)
Asymmetric encryption based on the algebraic structure of elliptic curves over finite fields. Offers similar security to RSA with smaller key sizes, generally ranging from 160 to 521 bits.
PGP (Pretty Good Privacy)
A data encryption and decryption program that provides cryptographic privacy and authentication. It uses a combination of symmetric and asymmetric encryption, often employing RSA for keys which might range from 1024 to 4096 bits.
