Most managed databases enable **encryption at rest** by default. But encryption at rest probably doesn't protect data in the way you think it does.

Queries on encrypted columns are encrypted in the same way.
Alongside the randomized ciphertext, the [Encrypt Query Language][eql] (EQL) package stores encrypted index terms that Postgres can compare without ever seeing plaintext. The terms reveal equality, ordering, and match relationships to the database, but not the values themselves.
Standard B-tree and GIN indexes work on those terms: in our [benchmarks][benchmarks], encrypted lookups run in 0.1–0.8 ms — equality through JSON containment — on tables of up to 10 million rows.

CipherStash @cipherstash/stack-prisma/runtime serialized encrypted values opaque placeholder redacted representation JSON serialization

💡 Result:

In the CipherStash ecosystem, specifically when using @cipherstash/stack-prisma/runtime, encrypted values are represented by specialized envelope classes (such as EncryptedString, EncryptedDouble, etc.) [1][2]. When these encrypted objects are serialized—for example, via JSON.stringify or when inspected in contexts like console.log—they automatically resolve to an opaque placeholder representation [1]. This design prevents sensitive plaintext from being accidentally exposed in application logs, JSON API responses, or other serialised outputs [1]. To access the original plaintext, you must explicitly call the.decrypt method on the encrypted object or use utility functions like decryptAll on a result set [1][3][4]. This ensures that decryption is a deliberate, code-level action [1]. Under the hood, these values are stored in the database as a JSON-based structure called a CipherCell, which contains the encrypted data, searchable metadata, and other administrative fields required for operations [5]. Application code interacts with these high-level envelope classes, while the underlying CipherCell format remains an implementation detail that users typically do not need to interact with directly [6].

CipherStash platform Access Intelligence access-event logging

💡 Result:

CipherStash Access Intelligence refers to the platform's capability to make data access decisions observable, allowing security teams, auditors, and developers to monitor and understand data access patterns, including the who, what, when, why, and under what authority data was accessed [1]. This functionality builds upon the platform's core audit logging and encryption-in-use features [2][1]. The platform's approach to access-event logging is characterized by the following: Core Logging Components: The CipherStash platform, particularly when using CipherStash Proxy, generates comprehensive data access events [3]. These events typically include: - Identity: The authenticated user or service performing the action (derived from Lock Contexts) [2][4]. - Operation Details: The specific action taken (e.g., encrypt, decrypt) [2]. - Scope: Which encrypted columns or records were accessed [2][4]. - Timing: Precise timestamps of when the operation occurred [3][2]. - Context: The application environment and query patterns used [2][5]. Advanced Proxy Audit Features: CipherStash Proxy enhances these logs through a transparent, automated pipeline that does not require instrumentation of application SQL code [3][6]: - Statement Fingerprinting: Automatically identifies unique SQL query patterns [3][2]. - SQL Redaction: Strips sensitive values from logged queries to maintain privacy [3][2]. - Primary Key Injection: Transparently injects missing primary keys into SQL statements to ensure accurate tracking of which specific records are accessed [3][2]. - Record Reconciliation: Maps extracted identifiers to specific database tables, ensuring the audit trail reflects exact record-level access [3][2]. Cryptographic Verifiability: A key distinction of the CipherStash audit trail is its cryptographic foundation [2]. Because access is controlled via identity-bound keys (ZeroKMS) and Lock Contexts, the resulting logs are not merely circumstantial application logs, but provide a cryptographically verifiable proof of access [2][7][5]. This ensures that access events cannot be easily falsified or bypassed, aiding in regulatory compliance (e.g., GDPR, HIPAA, SOC 2) [2][4]. Essentially, Access Intelligence leverages these immutable, cryptographically proven event logs to provide high-level observability into the security posture of sensitive data [1][8][9].
