+[RFC SULA-ALUS: A REVERSAL ENCRYPTION ALGORITHM]{align="center"}
+
+# Status of This Memo
+
+This memo provides information for the Internet community. It does not
+specify an Internet standard of any kind. Distribution of this memo is
+unlimited.
+
+# Abstract
+
+This document describes the SULA-ALUS encryption algorithm---a
+lightweight, reversible transformation whose principal operation is to
+reverse the input plaintext. The algorithm's name pays homage to the
+Latvian wordplay where reversing "sula" gives "alus." Although trivial
+in its operation, this algorithm may serve educational, demonstrative,
+or low-risk obfuscation purposes.
+
+# Introduction
+
+The SULA-ALUS algorithm is founded on a straightforward principle:
+encryption is performed by reversing the order of characters (or bytes)
+of the input data. While the transformation is simple and not intended
+for modern security-critical applications, it can be useful in contexts
+where a reversible obfuscation method is acceptable or for educational
+purposes.
+
+# Conventions Used in This Document
+
+The key words "MUST," "SHOULD," and "MAY" are to be interpreted as
+described in RFC 2119 [@rfc-2119].
+
+# The Reversal Encryption Algorithm
+
+The core idea behind SULA-ALUS is that the encryption operation is
+identical to the decryption operation -- they both consist of reversing
+the input sequence.
+
+## Encryption Process
+
+Let $P$ represent the plaintext composed of a sequence of characters:
+$$P = p_{1},p_{2},\ldots,p_{n}$$
+
+The ciphertext $C$ is produced by applying the reversal transformation:
+$$C = \text{ reverse}(P) = p_{n},p_{n - 1},\ldots,p_{1}$$ For example,
+if $P = \text{ sula}$, then: $$C = \text{ alus }$$
+
+## Decryption Process
+
+Given that the reversal operation is an involution (its own inverse),
+the decryption process involves applying the same transformation. Let
+$C$ be the ciphertext; then the plaintext $P$ is recovered as:
+$$P = \text{ reverse}(C)$$
+
+# Implementation Considerations
+
+A simple pseudocode implementation of the algorithm is as follows:
+
+    function encrypt(plaintext):
+    return reverse(plaintext)
+
+    function decrypt(ciphertext):
+    return reverse(ciphertext)
+
+This algorithm may be implemented in any programming language. It is
+important to note that due to its simplicity, SULA-ALUS is only
+appropriate for applications where robust cryptographic security is not
+a requirement.
+
+# Security Considerations
+
+The SULA-ALUS algorithm offers minimal protection and should not be used
+as a substitute for established cryptographic methods. Its reversible
+nature and lack of key-dependent randomness make it vulnerable to
+trivial analysis and brute-force reversal. Users are cautioned against
+employing this algorithm in scenarios where the confidentiality or
+integrity of sensitive data is paramount.
+
+# IANA Considerations
+
+This document has no actions for the Internet Assigned Numbers Authority
+(IANA).
+
+# Acknowledgments
+
+The authors thank the community for insights into minimalist
+cryptographic mechanisms and for inspiring creative approaches that
+celebrate cultural references---in this case, the reversal of the
+Latvian word "sula" to "alus."
