- MD5
- The MD5 (Message Digest) algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed in text format as a 32 digit hexadecimal number.
- MD5 has been utilized in a wide variety of cryptographic applications, and is also commonly used to verify data integrity.
- MD5 is not collision resistant and several flaws were found in the design of MD5.
- MD5 is considered cryptographically broken and is unsuitable for further use.
- SHA1
- SHA1 (Secure Hash Algorithm) is a cryptographic hash function designed by the National Security Agency (NSA).
- SHA1 produces a 160-bit (20-byte) hash value, typically rendered as a hexadecimal number, 40 digits long.
- SHA1 is the most widely used of the existing SHA hash functions, and is employed in several widely used applications and protocols.
- The SHA1 algorithm might not be secure enough for ongoing use. It is recommended not to use SHA1.
- SHA256
- SHA256 (Secure Hash Algorithm) is a cryptographic hash function designed by the National Security Agency (NSA).
- SHA256 produces a 256-bit (32-byte) hash value, typically rendered as a hexadecimal number, 64 digits long.
