+## Does Unicorn support ARM PAC (Pointer Authentication)?
+
+Yes! However, Unicorn by default disables it and enabling it involves a few coding and document reading.
+
+TLDR:
+
+Taken from [#1789](https://github.com/unicorn-engine/unicorn/issues/1789).
+
+```C
+    uc_arm64_cp_reg reg;
+
+    // SCR_EL3
+    reg.op0 = 0b11;
+    reg.op1 = 0b110;
+    reg.crn = 0b0001;
+    reg.crm = 0b0001;
+    reg.op2 = 0b000;
+
+    err = uc_reg_read(uc, UC_ARM64_REG_CP_REG, &reg);
+    assert(err == UC_ERR_OK);
+
+    // NS && RW && API
+    reg.val |= (1 | (1<<10) | (1<<17));
+
+    err = uc_reg_write(uc, UC_ARM64_REG_CP_REG, &reg);
+    assert(err == UC_ERR_OK);
+
+    // SCTLR_EL1
+    reg.op0 = 0b11;
+    reg.op1 = 0b000;
+    reg.crn = 0b0001;
+    reg.crm = 0b0000;
+    reg.op2 = 0b000;
+
+    err = uc_reg_read(uc, UC_ARM64_REG_CP_REG, &reg);
+    assert(err == UC_ERR_OK);
+
+    // EnIA && EnIB
+    reg.val |= (1<<31) | (1<<30);
+
+    err = uc_reg_write(uc, UC_ARM64_REG_CP_REG, &reg);
+    assert(err == UC_ERR_OK);
+    
+    // HCR_EL2
+    reg.op0 = 0b11;
+    reg.op1 = 0b100;
+    reg.crn = 0b0001;
+    reg.crm = 0b0001;
+    reg.op2 = 0b000;
+
+    // HCR.API
+    reg.val |= (1ULL<<41);
+
+    err = uc_reg_write(uc, UC_ARM64_REG_CP_REG, &reg);
+    assert(err == UC_ERR_OK);

+## I debug my application but soon get an access violation inside unicorn.
+
+This is intended for Windows. See discussion in [#1841](https://github.com/unicorn-engine/unicorn/issues/1841).

 ## My code does not do what I would expect - is this a bug?
