3ncr.org is a standard for string encryption/decryption (algorithms + storage format). Originally it was intended for encryption tokens in configuration files. It may be used to encrypt any UTF-8 strings.
3ncr.org v1 uses AES-256-GCM for encryption, PKDBF2 with SHA3 for key derivation, base64 for encoding binary data back to string. It is fairly simple:
header + base64(iv + aes-256-gcm(data) + tag)
Encrypted data looks like this 3ncr.org/1#I09Dwt6q05ZrH8GQ0cp+g9Jm0hD0BmCwEdylCh8
