The law on the electronic and digital signature is Law 27269. This law refers to electronic signatures and digital signatures:
- Electronic signature: Refers to any symbol based on electronic means used or adopted by a given party with the precise intention of linking or authenticating a document so that it meets the features of a handwritten signature.
- Digital signature: Refers to an electronic signature that uses a symmetric cryptography technique, based on the use of key pair that are unique ; a private key and a public key which are mathematically linked to each other, so that people who have access to the public key cannot retrieve the private key from it.
Both can be linked to the signatories, as the e-signature also has the same validity as the handwritten signature.
