B) Message Digest 5
C) RC4
D) Twofish

Message Digest 5 (MD5) is a cryptographic hash function that produces a 128-bit hash value. It is commonly used in virtual private networks (VPNs) to secure data transmission. MD5 makes a single pass on data and generates a 32-character hexadecimal number, which is used to verify the integrity of the transmitted data. RSA is a public key cryptosystem, RC4 is a symmetric stream cipher, and Twofish is a symmetric block cipher, none of which are used to generate a 128-bit hash value.
